NOTES TO CONDENSED FINANCIAL STATEMENTS

(Unaudited)

Periods of Three Months ended March 31, 2010 and March 31, 2009

Note A – BASIS OF PRESENTATION

The accompanying unaudited condensed financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X.  Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements.  In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included.  Operating results for the periods stated above are not necessarily indicative of the results that may be expected for each respective full year.  For further information, refer to the financial statements and footnotes included in the Great Northern Iron Ore Properties (“Trust”) Annual Report on Form 10-K for th e year ended December 31, 2009. 

Note B – SECURITIES

United States Treasury securities are classified as “held-to-maturity” securities and are carried at cost, adjusted for accrued interest and amortization of premium or discount.  The aggregate fair values listed in the table below are based on quoted prices in active markets for identical assets (Level 1).  Securities recognized as current assets will mature within one year of the respective period ending date stated below.  Securities recognized as noncurrent assets will mature one to three years from the respective period ending date stated below.  Following is an analysis of the securities as of periods stated:

	Current				Noncurrent
	March 31, 2010		Dec. 31, 2009		March 31, 2010		Dec. 31, 2009

Note C – PENSION PLAN

A summary of the components of net periodic pension cost for the three months ended March 31 is as follows:

	2010		2009
Service cost	$	61,606	$	57,233
Interest cost		79,667		86,888
Expected return on assets		-96,746		-81,772
Amortization of net loss		54,429		66,581
Amortization of prior service cost		4,367		4,367
Net periodic pension cost	$	103,323	$	133,297

The Trust had previously disclosed in its Annual Report as of December 31, 2009, that the next contribution to the plan for 2010 is estimated to approximate $625,000, subject to the plan’s annual actuarial valuation performed as of the plan’s fiscal year-end, March 31.  No additional updated information is available at this time. 

Note D – BENEFICIARIES’ EQUITY

Pursuant to the Court Order of November 29, 1982, the Trustees were directed to create and maintain an account designated as “Principal Charges.”  This account constitutes a first and prior lien of certificate holders on any property transferable to the reversioner and reflects an allocation of beneficiaries’ equity between the certificate holders and the reversioner.  This account is neither an asset nor a liability of the Trust.  Rather, this account maintains and represents a balance which will be payable to the certificate holders of record from the reversioner at the end of the Trust.  The balance in this account consists of attorneys’ fees and expenses of counsel for adverse parties pursuant to the Court Order in connection with litigation commenced in 1972 relating to the Trustees’ powers and duties under the Trust Agreement and the cost s of homes and surface lands acquired in accordance with provisions of a lease with United States Steel Corporation, net of an allowance to amortize the cost of the land based on actual shipments of taconite and net of a credit for disposition of tangible assets.  Following is an analysis of this account as of March 31, 2010:

Attorneys’ fees and expenses	$	1,024,834
Cost of surface lands		6,254,165
Cumulative shipment credits		-2,001,271
Cumulative asset disposition credits		-372,124
Principal Charges account balance	$	4,905,604

Upon termination of the Trust, the Trustees shall either sell tangible assets or obtain a loan with tangible assets as security to provide monies for distribution to the certificate holders in the amount of the Principal Charges account balance.

Total other comprehensive income		58,796		70,948
Total comprehensive income	$	2,379,818	$	4,501,825

Note F – Recently Adopted Accounting Standards

In January 2010, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2010-06, “Fair Value Measurements and Disclosures (Topic 820) - Improving Disclosures about Fair Value Measurements.”  This ASU requires some new disclosures and clarifies some existing disclosure requirements about fair value measurements as set forth in Accounting Standards Codification (“ASC”) Subtopic 820-10.  The FASB’s objective is to improve these disclosures and, thus, increase the transparency in financial reporting.  The Trust adopted the provisions of ASU 2010-06, effective January 1, 2010; however, the adoption of this ASU had no impact on the Trust’s financial statements.

Item 2.      Management’s Discussion and Analysis of Financial Condition and Results of Operations

Periods of Three Months ended March 31, 2010 and March 31, 2009

The Trust owns interest in 12,033 acres on the Mesabi Iron Range Formation in northeastern Minnesota, most of which are under lease to major iron ore producing companies.  Due to the Trustees’ election pursuant to Section 646 of the Tax Reform Act of 1986, as amended, commencing with year 1989 the Trust is not subject to federal and Minnesota corporate income taxes.  The Trust is now a grantor trust.  Shares of beneficial interest in the Trust are traded on the New York Stock Exchange under the ticker symbol “GNI” (CUSIP No. 391064102).

The terms of the Great Northern Iron Ore Properties Trust Agreement, created December 7, 1906, state that the Trust shall continue for twenty years after the death of the last survivor of eighteen persons named in the Trust Agreement.  The last survivor of these eighteen persons died on April 6, 1995.  Accordingly, the Trust terminates twenty years from April 6, 1995, that being April 6, 2015.

At the end of the Trust on April 6, 2015, the certificates of beneficial interest (shares) in the Trust will cease to trade on the New York Stock Exchange and thereafter will represent only the right to receive certain distributions payable to the certificate holders of record at the time of the termination of the Trust.  Upon termination, the Trust is obligated to distribute ratably to these certificate holders the net monies remaining in the hands of the Trustees (after paying and providing for all expenses and obligations of the Trust), plus the balance in the Principal Charges

-6-

account (this account is explained in the Trust’s Annual Report sent to all certificate holders every year).  All other Trust property (most notably the Trust’s mineral properties and the active leases) must be conveyed and transferred to the reversioner (currently Glacier Park Company, a wholly owned subsidiary of ConocoPhillips) under the terms of the Trust Agreement.

We have previously provided information in our various Securities and Exchange Commission filings, including our Annual Report, about the final distribution payable to the certificate holders upon the Trust’s termination.  The exact final distribution, though not determinable at this time, will generally consist of the sum of the Trust’s net monies (essentially, total assets less liabilities and properties) and the balance in the Principal Charges account, less any and all expenses and obligations of the Trust upon termination.  To offer a hypothetical example, without factoring in any expenses and obligations of the Trust upon its termination, and using the financial statement values as of December 31, 2009, the net monies were approximately $7,867,000 and the Principal Charges account balance was approximately $4,931,000, resulting in a final distribution payable of approximately $12,798,000, or about $8.53 per share.  After payment of this final distribution, the certificates of beneficial interest (shares) would be cancelled and have no further value.  It is important to note, however, that the actual net monies on hand and the Principal Charges account balance will most likely fluctuate during the ensuing years and will not be “final” until after the termination and wind-down of the Trust.  The Trust offers this example to further inform investors about the conceptual nature of the final distribution and does not imply or guarantee a specific known final distribution amount.

Results of Operations:

Royalties decreased $2,120,010 during the three months ended March 31, 2010, as compared to the same period in 2009, due mainly to less tonnage mined from Trust lands.

At their meeting held on March 22, 2010, the Trustees declared a distribution of $2.00 per share, amounting to $3,000,000 payable April 30, 2010, to certificate holders of record at the close of business on March 31, 2010.  At their meeting held on March 10, 2009, the Trustees declared a distribution of $1.80 per share, amounting to $2,700,000 paid on April 30, 2009, to certificate holders of record at the close of business on March 31, 2009.  The Trustees intend to continue quarterly distributions and set the record date as of the last business day of each quarter.  The next distribution will be paid in late July 2010 to certificate holders of record on June 30, 2010.

A mining agreement dated January 1, 1959, with United States Steel Corporation provides that one-half of annual earned royalty income, after satisfaction of minimum royalty payments, shall be applied to reimburse the lessee for a portion of its cost of acquisition of surface lands overlying the leased mineral deposits, which surface lands are then conveyed to the Trustees.  There are surface lands yet to be purchased, the costs of which are yet unknown and will not be known until the actual purchases are made.

Liquidity:

In the interest of preservation of principal of Court-approved reserves and guided by the restrictive provisions of Section 646 of the Tax Reform Act of 1986, as amended, monies are invested primarily in U.S. Treasury securities with maturity dates not to exceed three years and, along with cash flows from operations, are deemed adequate to meet currently foreseeable liquidity needs.

Item 3.     Quantitative and Qualitative Disclosures About Market Risk

– None

Item 4.     Controls and Procedures

As of the end of the period covered by this report, the Trust conducted an evaluation, under the supervision and with the participation of the Chief Executive Officer and Chief Financial Officer, of the Trust’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities and Exchange Act of 1934 (the “Exchange Act”)).  Based on this evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the Trust’s disclosure controls and procedures are effective to ensure that information required to be disclosed by the Trust in reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission rules and forms.  There was no change in the Trust’s internal control over financial reporting duri ng the Trust’s most recently completed fiscal quarter that has materially affected, or is reasonably likely to materially affect, the Trust’s internal control over financial reporting.
