Geologic map of the Bend 30- x 60-minute quadrangle, central Oregon Geologic map of the Bend 30- x 60-minute quadrangle, central Oregon
This map presents the stratigraphic and structural setting of volcanic and sedimentary strata deposited during the past 35 million years across 4,430 km2 in central Oregon. Snowfall in the Cascade Range (west part of map area) recharges important aquifers in the Deschutes basin (central part of map). The area includes the majestic peaks of the Three Sisters volcanoes, where continued...
Geologic map of the Hasty Quadrangle, Boone and Newton Counties, Arkansas Geologic map of the Hasty Quadrangle, Boone and Newton Counties, Arkansas
This digital geologic map compilation presents new polygon (for example, geologic map unit contacts), line (for example, fault, fold axis, and structure contour), and point (for example, structural attitude, contact elevations) vector data for the Hasty 7.5-minute quadrangle in northern Arkansas. The map database, which is at 1:24,000-scale resolution, provides geologic coverage of an...
