Between Dec 19, 2024 and Jan 2, 2025, datasets can be submitted to DRUM but will not be processed until after the break. Staff will not be available to answer email during this period, and will not be able to provide DOIs until after Jan 2. If you are in need of a DOI during this period, consider Dryad or OpenICPSR. Submission responses to the UDC may also be delayed during this time.

    Bedrock Geologic Map of the Central Wilder Lake Intrusion, Lake County, Minnesota
    (2013-08) Smith, John; Leu, Adam
    This study was done in an attempt more accurately define lithologic boundaries in the central area of the wilder lake intrusion. Data from a 2012 PRC capstone project, Adam Leu’s masters thesis, and previous mapping projects were used to map the western and eastern margins of the intrusion, leaving the middle section mostly inferred. The upper map shows the entirety of the wilder lake intrusion at a 1 to 24,000 scale and the lower map shows the area of interest at a 1 to10,000 scale. John Smith and Adam Leu spent five days camping on the edge of South WIlder Lake, traversing through areas with little to no lithologic data. Since the pagami creek burn had cleared out most of the the vegetation, the primary obsticals were dead fall and marshes. 160 outrops were mapped, but since the main goal was to better define lithologic boundaries, many outcrops that didn’t relate to a change in rock type were not put on the map.

    Bedrock Geologic Map of the Gafvert Lake Area, St. Louis County, Northeastern Minnesota
    (2013-08) Baumgardner, Mark; Brown, Nathan; Grotte, Matt; Jacobson, Alan; Kendall, Jamie; Ostwald, Claire; Schriner, Nathan; White, Justin; Peterson, Dean M
    This project was carried out under the supervision of Dean Peterson, Vice President of Exploration at Duluth Metals with the goal of creating a higher-resolution bedrock map of the Gafvert Lake area. The area was last mapped in 2003 at the 1:100,000 scale by the Minnesota Geological Survey (Jirsa and Boerboom, 2003). Mapping was carried out over five days by eight students for the 2013 Precambrian Field Camp. Six hundred and seventeen outcrops were mapped by hiking and lakeshore canoe mapping. The final map incorporated over 1,500 outcrops from historical work in the area. Emphasis was placed on defining the structure of an Archean stratovolcano within the Vermilion Greenstone Belt.

    Bedrock Geology of the Hanson Lake Mapping Area
    (2013-08) Mucahy, Connor; Romanelli, Daniel; May, Mitchell; Schulz, Roger; Moorhead, Steven; Jirsa, Mark J
    This map was created by PRC Field Camp students under the guidance of Mark Jirsa, M.Sc., Senior Geologist, Minnesota Geological Survey. The purpose of this map is to further understand the geology of the Hanson Lake area, with special focus on the sedimentary and structural history of Archean and Proterozoic bedrock. This map is the product of seven days of field mapping by the authors in August 2013. Outcrops were mapped by canoe along shorelines and by foot along inland traverses within the Dutton Lake, Ester Lake, Kekekabic Lake, and Ogishkemuncie Lake quadrangles. Although the field mapping was carried out on 1:24,000 scale maps, the digitization of data allowed this map to be produced at a 1:12,000 scale. It is the first detailed geologic map of the area to be produced at this scale.

    Bedrock Geology of the Lake Three Troctolite in the Pagami Creek Burn Area BWCAW Lake County Minnesota
    (2013-08) Benningfield, Jordan; Graham, Jackson; Kozmor, Sara; Prue, Ann Marie; Sauer, Sarah; Miller, James
    This map was produced based on 420 outcrops which were mapped over a four day period under the supervision of Dr. James D. Miller. Four students along with a TA and Dr. Miller mapped the southern shore of Lake Three of the Boundary Waters Canoe Area Wilderness, Lake County, Minnesota in order to establish a better understanding of the contact relationships of the Anorthositic Series of the Duluth Complex and the Lake Three Troctolite which is a discrete unit of the Layered Series of the Duluth Complex. Building on previous shoreline mapping (Miller, J.D., 1986), several traverses inland were completed to determine the extent of the Lake Three Troctolite, establish the contacts with the Anorthositic Series and describe the internal structure and lithology of the Lake Three Troctolite. Based on the four days of field work this 1: 10,000 scale map and cross section were produced for use in future research projects.
