What does this data set describe?

Title:
Bedrock Geologic Map of the Yucca Mountain Area, Nye County, Nevada
Abstract:
Yucca Mountain, Nye County, Nevada, has been identified as a potential site for underground storage of high-level radioactive nuclear waste. Detailed bedrock geologic maps form an integral part of the site characterization program by providing the fundamental framework and structural setting for the area in and adjacent to the site of the potential repository.

Why was the data set created?

This 1:24,000-scale map focuses on the area surrounding the potential high-level nuclear wast repository site at Yucca Mountain. Its purpose is to define the character and extent of the dominant structural features in the vicinity of and outward from the potential repository area. The Yucca Mountain Project currently is evaluating the cumulative effect of natural geologic hazards in the site area, including seismic and volcanic hazards.
