How deep is the gully cut by the ephemeral stream (shown with a dashed blue line) that flows down the Trail Canyon alluvial fan where it crosses the “sea level” contour at the bottom of the fan?

The question is based on Map T-10, the “Furnace Creek, California” quadrangle (scale 1:62,500; contour interval 80 feet; dotted lines represent 20-foot contours). This portion of the Furnace Creek quadrangle shows the Panamint Range and the western side of Death Valley in Death Valley National Park (36°19'08"N, 116°53'25"W). Several large alluvial fans can be seen along the eastern front of the Panamint Range. The basin floor here is called the Death Valley “salt pan,” because salts have accumulated here in great thicknesses.
What will be an ideal response?


about 5 feet deep
