Continuing on the east side of the main park road, just north of the Tower of Babel, Lower Courthouse Wash extends a short distance to the east before curving to the south.
This part of the wash cuts deep into the Navajo and Kayenta Formations where most of the arches in this area are found. The canyon continues south another three miles before dumping into the Colorado River.
Classified as a cliff wall arch and with a light opening of 41 feet, Streaked Arch is the largest arch in Lower Courthouse Wash.
