Title II: Minnesota Public Lands - Minnesota Public Lands Improvement Act of 1990 - Grants to Minnesota the right, title, and interest of the United States in and to certain public uplands and islands in Minnesota waters which were not subject to any claim as of 180 days after enactment of this Act. Allows the Secretary of the Interior to sell certain other lands which were subject to a claim identified on the records of the Bureau of Land Management as of that date to the claimants following resolution of conflicting claims except in certain circumstances. Deems title to public lands which, on the date of enactment of this Act, were subject to leases issued to Minnesota under the Recreation and Public Purposes Act to have vested in the State and to be exempt from Department of the Interior regulations governing leases under such Act. Allows the State to receive, under this Act, lands previously patented to the State under such Act by notifying the Secretary that it intends to relinquish such lands to the United States. Requires the Secretary to transfer such lands back to the State subject to the provisions of this Act, effective simultaneously with the State's relinquishment of such lands. Authorizes the Secretary to sell and issue a patent to a tract of public land located in Minnesota where the Secretary determines that: (1) such tract does not exceed 1,500 acres and is difficult and uneconomic to manage as part of the public lands and is not suitable for management by another Federal department or agency; and (2) such sale would not be inconsistent with land use plans developed in accordance with the Federal Land Policy and Management Act of 1976. Allows the Secretary, following adjudication of any claims, to convey such land at fair market value, less equities presented by an applicant for such conveyance (such as the amount paid for the land, longevity of the applicant's claim, and taxes paid on the land) and less the value of any improvements. Provides for description of tracts of such land conveyed on the approved Federal plat of survey. Authorizes the Secretary to either: (1) convey title to a qualified trustee, where a tract does not conform to an existing survey plat, in order to conform the legal description to such plat; or (2) require the applicant to reimburse the United States for the cost of preparing a plat of survey. Prohibits the sale of such lands unless the Secretary, before 30 days prior to such sale, publishes notice in a newspaper of general circulation in the county where the tract is located. Reserves to the United States all mineral rights in the lands transferred under this Act. Prohibits the conveyance or transfer of such lands by Minnesota to any person or entity other than the United States or a political subdivision of the State.
