     This prospectus is part of a registration statement that we filed with the
Securities and Exchange Commission, which we refer to as the "SEC", as a
"well-known seasoned issuer" as defined in Rule 405 under the Securities Act of
1933, as amended, utilizing a "shelf" registration process. Under this shelf
registration process, we may offer and sell our common stock described in this
prospectus in one or more offerings. Each time we offer our common stock, we
will provide a prospectus supplement and attach it to this prospectus. The
prospectus supplement will contain specific information about the terms of the
offering. The prospectus supplement may also add, update or change information
contained in this prospectus. You should read both this prospectus and any

                                  RISK FACTORS

     You should carefully consider the specific risks set forth under "Risk
Factors" in the applicable prospectus supplement and under the caption "Risk
Factors" in any of our filings with the SEC pursuant to Sections 13(a), 13(c),
14 or 15(d) of the Securities Exchange Act of 1934 incorporated herein by
reference, before making an investment decision.

                                 USE OF PROCEEDS

     We will use the new proceeds from our sale of the common stock for general
corporate purposes, which may include repaying indebtedness, making additions to
our working capital, funding future acquisitions, or for any other purpose we
describe in the applicable prospectus supplement.

                              PLAN OF DISTRIBUTION

     We may sell the common stock to one or more underwriters for public
offering and sale by them and may also sell the common stock directly or through
agents. We will name any underwriter or agent involved in the offer and sale of
common stock in the applicable prospectus supplement. We have also reserved the
right to sell or exchange securities directly to investors on our own behalf in
those jurisdictions where we are authorized to do so.

     We may distribute the common stock from time to time in on or more
transactions (i) at a fixed price; (ii) at market prices prevailing at the time
of sale; (iii) at prices related to such prevailing market prices, or (iv) at
negotiated prices.

                                       3

     We may also, from time to time, authorize dealers, acting as our agents, to
offer and sell common stock upon the terms and conditions set forth in the
applicable prospectus supplement. In connection with the sale of common stock,
we, or the purchasers of securities for whom the underwriters may act as agents,
may compensate the underwriters in the form of underwriting discounts or
commissions. Underwriters may sell the securities to or through dealers, and
those dealers may receive compensation in the form of discounts or commissions
from the underwriters and/or commissions from the purchasers for whom they may
act as agent. Unless otherwise indicated in a prospectus supplement, an agent
will be acting on a best efforts basis and a dealer will purchase securities as
a principal, and may resell the securities at varying prices to be determined by
the dealer.

     We will describe in the applicable prospectus summary any compensation we
pay to underwriters or agents in connection with the offering of securities, and
any discounts, concessions or commissions allowed by underwriters to
participating dealers. Dealers and agents participating in the distribution of
securities may be deemed to be underwriters, and any discounts and commissions
received by them and any profit realized by them on the resale of securities may
be deemed to be underwriting discounts and commissions. We may enter into
agreements to indemnify underwriters, dealers and agents against certain civil
liabilities, including liabilities under the Securities Act, and to reimburse
them for certain expenses.

     To facilitate the offering of securities, certain persons participating in
the offering may engage in transactions that stabilize, maintain, or otherwise
affect the price of the securities. This may include over-allotments or short
sales of securities, which involve the sale by persons participating in the
offering of more securities than we sold to them. In these circumstances, these
persons would cover such over-allotments or short positions by making purchases
in the open market or by exercising their over-allotment option, if any. In
addition, these persons may stabilize or maintain the price of the securities by
bidding for or purchasing securities in the open market or by imposing penalty
bids, whereby selling concessions allowed to dealers may be reclaimed if
securities sold by them are repurchased in connection with stabilization
transactions. The effect of these transactions may be to stabilize or maintain
the market price of the securities at a level above that which might otherwise
prevail in the open market. These transactions may be discontinued at any time.

     Certain of the underwriters, dealers or agents and their associates may
engage in transactions with or perform services for us in the ordinary course of
their business for which they receive compensation.

                                  LEGAL MATTERS

     Unless otherwise specified in the applicable prospectus supplement, the
validity of the common stock will be passed upon for us by Christensen, Moore,
Cockrell, Cummings & Axelberg, P.C., and will be passed upon for any agents,
dealers or underwriters by counsel named in the applicable prospectus
supplement.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Sections 35-1-451 through 35-1-459 of the Montana Business Corporation Act
("MBCA") contain specific provisions relating to indemnification of directors
and officers of Montana corporations. In general, the statute provides that (i)
a corporation must indemnify a director or officer who is wholly successful in
his defense of a proceeding to which he is a party because of his status as
such, unless limited by the articles of incorporation, and (ii) a corporation
may indemnify a director or officer if he is not wholly successful in such
defense, if it is determined as provided in the statute that the director meets
a certain standard of conduct, provided that when a director is liable to the
corporation, the corporation may not indemnify him. The statute also permits a
director or officer of a corporation who is a party to a proceeding to apply to
the courts for indemnification or advance of expenses, unless the articles of
incorporation provide otherwise, and the court may order indemnification or
advancement of expenses under certain circumstances set forth in the statute.
The statute further provides that a corporation may in its articles of
incorporation or bylaws or by resolution provide indemnification in addition to
that provided by statute, subject to certain conditions set forth in the
statute.

     The articles of incorporation of Glacier provide, among other things, that
the personal liability of the directors and officers of the corporation for
monetary damages shall be eliminated to the fullest extent permitted by the
MBCA. Glacier's bylaws provide that the corporation shall indemnify its
directors and officers to the fullest extent not prohibited by law, including
indemnification for payments in settlement of actions brought against a director
or officer in the name of the corporation.

ITEM 22. UNDERTAKINGS

     The undersigned registrant hereby undertakes:

     1. To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:

          (i) To include any prospectus required by Section 10(a)(3) of the
Securities Act of 1933;

          (ii) To reflect in the prospectus any facts or events arising after
the effective date of the registration statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in the registration
statement. Notwithstanding the foregoing, any increase or decrease in volume of
securities offered (if the total dollar value of securities offered would not
exceed that which was registered) and any deviation from the low or high end of
the estimated maximum offering range may be reflected in the form of prospectus
filed with the Securities and Exchange Commission pursuant to Rule 424(b) if, in
the aggregate, the changes in volume and price represent no more than a 20%
change in the maximum aggregate offering price set forth in the "Calculation of
Registration Fee" table in the effective registration statement; and

          (iii) To include any material information with respect to the plan of
distribution not previously disclosed in the registration statement or any
material change to such information in the registration statement; provided,
however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) above do not
apply if the registration statement is on Form S-3 and the information required
to be included in a post-effective amendment by those paragraphs is contained in
reports filed with or furnished to the Securities and Exchange Commission by the
registrant pursuant to section 13 or section 15(d) of the Securities Exchange
Act of 1934 that are incorporated by reference in the registration statement, or
is contained in a form of prospectus filed pursuant to Rule 424(b) that is part
of the registration statement.

                                      II-2

     2. That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

     3. To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

     4. That, for the purpose of determining liability under the Securities Act
of 1933 to any purchaser, if the registrant is relying on Rule 430B:

          (i) Each prospectus filed by the registrant pursuant to Rule 424(b)(3)
shall be deemed to be part of the registration statement as of the date the
filed prospectus was deemed part of and included in the registration statement;
and

          (ii) Each prospectus required to be filed pursuant to Rule 424(b)(2),
(b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B
relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for
the purpose of providing the information required by section 10(a) of the
Securities Act of 1933 shall be deemed to be part of and included in the
registration statement as of the earlier of the date such form of prospectus is
first used after effectiveness or the date of the first contract of sale of
securities in the offering described in the prospectus. As provided in Rule
430B, for liability purposes of the issuer and any person that is at that date
an underwriter, such date shall be deemed to be a new effective date of the
registration statement relating to the securities in the registration statement
to which that prospectus relates, and the offering of such securities at that
time shall be deemed to be the initial bona fide offering thereof. Provided,
however, that no statement made in a registration statement or prospectus that
is part of the registration statement or made in a document incorporated or
deemed incorporated by reference into the registration statement or prospectus
that is part of the registration statement will, as to a purchaser with a time
of contract of sale prior to such effective date, supersede or modify any
statement that was made in the registration statement or prospectus that was
part of the registration statement or made in any such document immediately
prior to such effective date.

     5. That, for the purpose of determining liability of the registrant under
the Securities Act of 1933 to any purchaser in the initial distribution of the
securities, the undersigned registrant undertakes that in a primary offering of
securities of the undersigned registrant pursuant to this registration
statement, regardless of the underwriting method used to sell the securities to
the purchaser, if the securities are offered or sold to such purchaser by means
of any of the following communications, the undersigned registrant will be a
seller to the purchaser and will be considered to offer or sell such securities
to such purchaser:

          (i) Any preliminary prospectus or prospectus of the undersigned
registrant relating to the offering required to be filed pursuant to Rule 424;

          (ii) Any free writing prospectus relating to the offering prepared by
or on behalf of the undersigned registrant or used or referred to by the
undersigned registrant;

          (iii) The portion of any other free writing prospectus relating to the
offering containing material information about the undersigned registrant or its
securities provided by or on behalf of the undersigned registrant; and (iv) Any
other communication that is an offer in the offering made by the undersigned
registrant to the purchaser.

                                      II-3

     6. For purposes of determining any liability under the Securities Act of
1933, each filing of the registrant's annual report pursuant to section 13(a) or
section 15(d) of the Securities Exchange Act of 1934 (and, where applicable,
each filing of an employee benefit plan's annual report pursuant to section
15(d) of the Securities Exchange Act of 1934) that is incorporated by reference
in the registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     7. To supplement the prospectus, after the expiration of the subscription
period, to set forth the results of the subscription offer, the transactions by
the underwriters during the subscription period, the amount of unsubscribed
securities to be purchased by the underwriters, and the terms of any subsequent
reoffering thereof. If any public offering by the underwriters is to be made on
terms differing from those set forth on the cover page of the prospectus, a
post-effective amendment will be filed to set forth the terms of such offering.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions set forth in response to Item 15, or
otherwise, the registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the
event that a claim for indemnification against such liabilities (other than the
payment by the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act of 1933 and will be governed by the final adjudication of such
issue.

                                      II-4

                                   SIGNATURES

     Pursuant to the requirements of the 1933 Act, the Registrant certifies that
it has reasonable grounds to believe that it meets all of the requirements for
filing on Form S-3 and has duly caused this Registration Statement to be signed
on its behalf by the undersigned, thereunto duly authorized, in the City of
Kalispell, State of Montana, on June 6, 2006.

Glacier Bancorp, Inc.

Kalispell, Montana 59901

     RE:  REGISTRATION STATEMENT ON FORM S-3

Ladies and Gentlemen:

     We have acted as special counsel for Glacier Bancorp, Inc., a Montana
corporation ("Glacier"), in connection with the registration under the
Securities Act of 1933, as amended (the "Act") of up to 2,000,000 shares of
Glacier common stock, $0.01 par value per share (the "Shares"), covered by the
above-referenced Registration Statement and any amendments thereto (the
"Registration Statement") filed by Glacier with the Securities and Exchange
Commission (the "Commission") under the Securities Act of 1933, as amended.

     In connection with the Shares that will be registered and issued under the
Registration Statement, we have examined the following: (i) the Registration
Statement and related form of prospectus included therein (the "Prospectus") to
be filed by Glacier with the Commission; (ii) resolutions adopted by the Board
of Directors of Glacier ("Board of Directors") relating to the authorization and
approval of the registration of the Shares under the Registration Statement; and
(iii) such other documents as we have deemed necessary to form the opinion
expressed below. As to various questions of fact material to such opinion, where
relevant facts were not independently established, we have relied upon
statements of officers of Glacier or representations of Glacier contained in the
Registration Statement. We have assumed without independent investigation or
review, the accuracy and completeness of the facts and representations and
warranties contained in the documents listed above or otherwise made known to
us.

     Our opinion assumes that the issuance of Shares covered by the Registration
Statement by Glacier from time to time will be approved by the Board of
Directors, in accordance with Montana law and the Articles of Incorporation and
Bylaws of Glacier (such approval being referred to herein as the "Corporate
Proceedings").

     Based upon and relying solely upon the foregoing, we advise you that in our
opinion, upon completion of all Corporate Proceedings relating to the Shares, or
any portion thereof, the

Glacier Bancorp, Inc.

Page 2

Shares will be (assuming that, upon issuance, the total number of Shares issued
and outstanding will not exceed the total number of Shares that Glacier is then
authorized to issue under its Articles of Incorporation) duly authorized and,
when and if delivered against payment therefor in accordance with the Corporate
Proceedings, will be validly issued under the laws of the State of Montana, and
will be fully paid and nonassessable.

     We assume no obligation to supplement this opinion if any applicable law
changes after the date hereof or if we become aware of any fact that might
change the opinion expressed herein after the date hereof.

     This opinion letter is limited to the application of the laws of the State
of Montana and the federal laws of the United States of America, and we express
no opinion as to the laws of any other jurisdictions.

     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the legal reference to this firm under the caption
"Certain Legal Matters" as having passed upon the validity of the Shares. In
giving such consent, we do not thereby admit that we are experts within the
meaning of the Act.

                                        Very truly yours,

                                        CHRISTENSEN, MOORE, COCKRELL, CUMMINGS
