Map showing spatial and temporal relations of mountain and continental glaciations on the Northern Plains, primarily in northern Montana and northwestern North Dakota Map showing spatial and temporal relations of mountain and continental glaciations on the Northern Plains, primarily in northern Montana and northwestern North Dakota
This report is an overview of glacial limits and glacial history on the plains in northern Montana and northeastern North Dakota (long 102?-114?W.) and also in adjacent southern Alberta and Saskatchewan, Canada. In the Rocky Mountains and on the plains adjacent to the mountains in Montana, the map also depicts spatial relations of valley glaciers and piedmont ice lobes to continental ice...
Map showing susceptibility to rainfall-triggered landslides in the municipality of Ponce, Puerto Rico Map showing susceptibility to rainfall-triggered landslides in the municipality of Ponce, Puerto Rico
The risk of landslides during intense or prolonged rainfall is high in steeply sloping areas such as the municipality of Ponce, where 56 percent of the 301-square-kilometer municipality has slopes 10 degrees or greater. These are areas where the possibility of landsliding increases when triggering conditions such as heavy rainfall or excavation and construction occur. Using a 30-meter...
Maps of Hawaiian Islands exclusive economic zone interpreted from GLORIA sidescan-sonar imagery Maps of Hawaiian Islands exclusive economic zone interpreted from GLORIA sidescan-sonar imagery
The map is geology around the Hawaiian Islands derived from GLORIA data collected in 1986-1989 from the southeastern Hawaiian Ridge EEZ (Exclusive Economic Zone), which covers more than 1,000,000 km2 of sea floor. The seafloor is characterized by a variety of volcanic and sedimentary processes. Cretaceous age seafloor underlies both subaerial and subaqueous erupted lava forming the...
