This metadata is for the vegetation and land-use geo-spatial database for Nez Perce National Historical Park (NEPE) with seven NPS sites in Idaho, Washington, Montana, Oregon and surrounding areas. This project is authorized as part of the USGS/NPS Vegetation Inventory Program. The program is being administered by the National Park Service's (NPS) Inventory and Monitoring Program in conjunction with the Biological Resources Division (BRD) of the United States Geological Survey (USGS). This mapping effort was performed by Cogan Technology Inc. (CTI) under contract to Northwest Management, Inc (NMI) and the Upper Columbia Basin Inventory and Monitoring Network (UCBN) of the National Park Service.

Album caption: Two generations of late plagioclase are seen in a specimen of quartz diorite about a mile north of Bruces Eddy. The ealier plagioclase was crystallized as large grains in biotite quartzite and gneiss, the remnants of which are seen at left. The large white grains in the diorite are remnants of the same early plagioclase. The small grains of plagioclase in the quartz diorite are later. Clearwater County, Idaho. c.1950. Published as figure 87 in U.S. Geological Survey. Professional paper 344-A. 1962.
