Review of the origin of the Braid Scarp near the Pebble prospect, southwestern Alaska
Peter J. Haeussler, Christopher F. Waythomas
2011, Open-File Report 2011-1028
A linear geomorphic scarp, referred to as the 'Braid Scarp,' lies about 5 kilometers north of Iliamna Lake, Alaska, and has been identified as a possible seismically active fault. We examined the geomorphology of the area and an 8.5-meter-long excavation across the scarp. We conclude that the scarp was formed...
