Maps showing mines, prospects, and mineral sites in the Tray Mountain Roadless Area and vicinity, Northern Georgia Maps showing mines, prospects, and mineral sites in the Tray Mountain Roadless Area and vicinity, Northern Georgia
The Tray Mountain Roadless Area, a 36,300-acre tract in the Chattahoochee National Forest, northeastern Georgia, lies within the Blue Redge physiographic province. The roadless area is composed of Precambrian(?)-age metamorphic rocks from two tectonic units, the Hayesville thrust sheet and the "Helen belt" (Nelson, 1982) (fig. 1). The Hayesville thrust sheet consists mostly of biotite...
Maps showing sea-floor topography, depth to bedrock, and sediment thickness, Penobscot Bay, Maine Maps showing sea-floor topography, depth to bedrock, and sediment thickness, Penobscot Bay, Maine
This report presents results of a high-resolution seismic-reflection survey conducted by the U.S. Geological Survey to determine the subbottom characteristics of Penobscot Bay, Maine. Penobscot Bay is one of the major embayments along the U.S. Atlantic coast (fig. 1), extending more than 50 km from the Gulf of Maine to the mouth of the Penobscot River. The bay constitutes an area of...
