MonitoringLocationTypeName River/Stream
MonitoringLocationDescriptionText Horn Creek consists of two primary branches. The west branch is usually dry, and the east branch has perennial flow in places. The sample site is in the east tributary about 500 m upstream from the Tonto Trail crossing where water discharges from the channel alluvium that overlies the Bright Angel Shale, within the boundary of Grand Canyon National Park. Water samples were collected at a small waterfall that was formed by boulders in the stream channel. Discharge was measured volumetrically at a small waterfall near the sample site. The spring flow emerges on the downthrown side of the northweststriking Salt Fault and flows intermittently to the Colorado River. At the head of the drainage is a breccia pipe and a historic uranium mine. Recent flooding has removed most of the vegetation at the site, leaving a few Fremont cottonwood trees in the nearby channel reach. The USGS site ID is 360443112083300. Site is located within the boundary of Grand Canyon National Park.
