Acceleration of the County Geologic Atlas Program II
This project will accelerate production of County Geologic Atlases (part A). An atlas is a set of geologic maps and associated databases for a county that facilitate informed management of natural resources, especially water and minerals.
This grant has supported progress on County Geologic Atlases for Cass, Isanti, Dodge, St. Louis, and Lake counties, and updates to the Hennepin and Washington Atlases.
$615,000 the first year and $615,000 the second year are for developing county geologic atlases. This appropriation is available until June 30, 2018.
Within the period of this grant substantial progress or completion of three county geologic atlases should be achieved. If more than three projects are conducted, proportionally less progress on each project will be achieved.
Databases of well construction data are finished for Cass, Isanti, Dodge, Hennepin, and Washington counties and work continues in St. Louis and Lake counties. The Washington CGA update should be complete in January of 2016. Compilation of the surficial geology maps for Isanti, Dodge, Hennepin, and Cass is underway. Drilling is underway for Cass County.
$615,000 the first year and $615,000 the second year are for developing county geologic atlases. This appropriation is available until June 30, 2018.
Each county geologic atlas costs about $350,000, so this $615,000 will fund about 1.75 atlases. As a practical matter, the funding is applied to many atlases which are partially funded by Legacy funds and partially funded by other sources.
The last stages of work for the Wadena, Redwood, and Brown CGAs are being funded. Redwood is being printed, and Wadena and Brown will follow closely. The Washington CGA has been printed and delivered. The Dodge, Lake, and St. Louis CGAs have been moved to other funding sources. The database for Dodge is complete and surficial and bedrock maps are under construction. The work in the Arrowhead has been divided into subprojects, and the first of three bedrock maps will be complete mid-summer. Another will follow in a year. The surficial geology has four subprojects and the first map will be complete late this year. The Hennepin CGA has been moved to other funding. The database work is nearly complete as is the surficial geology map. The bedrock map is also well along. The Cass and Isanti CGAs are the main focus of this funding stream currently. In Cass, drilling is complete and the surficial map will be drafted late this year. Bedrock work is also well underway. In Isanti County the database is complete, and the surficial and bedrock maps are very near completion. These phases are followed by work on the glacial subsurface mapping.
