Summary
This point shapefile represents ground observations collected by terrestrial laser scanner (TLS) surveys in Grapevine Canyon near Scotty's Castle, Death Valley National Park, from July 12-14, 2016, and filtered of extraneous data from features such as vegetation, fences, power lines, and atmospheric interference using an iterative process in I-Site Studio. The resulting 122,104 points were used to produce a digital terrain model of the area (GrapevineCanyon_TIN.zip in this data release).
Summary

The resulting 122,104 points were used to produce a digital terrain model of the area (GrapevineCanyon_TIN.zip in this data release).
These data were collected as part of a U.S. Geological Survey study, done in cooperation with the National Park Service, to assess the extent of potential flood-inundation areas in Grapevine Canyon near Scotty's Castle, Death Valley National Park, California. Regional flood regression equations were used to estimate the 4, 2, 1, 0.5, and 0.2 percent annual exceedance probability (AEP) flood streamflows. The estimated flood streamflows were used in the one-dimensional hydraulic model to compute water surface elevations mapped using the digital terrain model.
