Yellowstone Lake is the largest high-altitude lake in North America, at an altitude of 2,357 m with a surface area of 341 km2 (sheet 1). More than 140 rivers and streams flow into Yellowstone Lake. The Yellowstone River, which enters at the southern end of the Lake into the Southeast Arm (sheet 1), dominates the inflow of water and sediment. The only outlet from the lake is at Fishing Bridge where the Yellowstone River flows northward discharging 375 to 4,600 cubic feet per second. Purpose: Using the bathymetric and seismic data in addition to the high- resolution aeromagnetic data acquired in 1996 and previous on- land geologic mapping, a geologic map was prepared. Also various bathymetric perspectives of the lake floor have been included in sheet 2.

Native_Data_Set_Environment: SunOS, 5.8, sun4u UNIX ArcInfo version 9.2 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Multi-beam sonar mapping occurred over a four-year period beginning in 1999 through 2002. The multi-beam swath-bathymetric surveys employed a SeaBeam 1180 (180 kHz) instrument with a depth resolution of <1 percent of the water depth. Water depth in the survey areas varied from approximately 4 to 133 m. The multi-beam instrument used 126 beams arrayed over a 150 degree ensonification angle to map a swath width of 7.4 times water depth. The new survey, with locations controlled with <1 m both horizontally and vertically using differential GPS, utilized more than 244 million soundings to produce high-resolution continuous overlapping coverage of the lake's bathymetry. Logical_Consistency_Report: Seismic-reflection records of the upper 25 m of the lake bottom also were obtained in 1999, 2000, 2001, and 2003. The seismic reflection profiling utilized an EdgeTech SB-216S, that sweeps a frequency range from 2 to 10 kHz and has a beam angle of 15 degrees to 20 degrees. Bothe the swath-unit transducer and the sub-bottom seismic unit were rigidly mounted to the transom of the National Park Service RV "Cutthroat," an 8-m-long aluminum boat. Completeness_Report: Data are complete: no features were eliminated or generalized. Unit properties are described in the text explanation.
