Horseshoe Springs is an oasis in the desert west of Salt Lake City. Situated within the Skull Valley in an area of the desert north of the Dugway Proving Grounds and south of the Great Salt Lake, this warm-spring fed marsh is a haven for migratory birds and home to others more permanently. The warm springs that feed it are thought to derive there water from mountain runoff that percolates through the soil, is heated by the Earth, then mixed with cooler waters before making its way to the surface in the pools at the east end of the area -- very near the Skull Valley Road (UT-196) and across from the Skull Valley Offroad Camping Area.
The waters that feed the springs percolate through soils that have a noticeable salt content and the water then becomes somewhat brackish. Several species of fish live in the pools and channels that radiate away from the pools and fishing is allowed with a permit. Since water is scarce in the desert places like Horseshoe Springs are popular with wildlife -- particularly birds during migration. About 60-65 miles south of Horseshoe Springs is Fish Springs National Wildlife Refuge at the southern edge of the Dugway Proving Grounds exclusion zone.
The waters that well up in the pools then move in a westerly direction into slightly lower ground before heading north to the Great Salt Lake.
Just north and beyond the Springs are a small ranch that raises about 50 head of cattle. Much further south is a much larger ranch with hundreds of cattle. In this video I fly my drone, and Phantom 4 Pro, over and around the Springs and also a bit further north towards the small ranch.
I make note in the video that care was taken to avoid disturbing the wildlife with the drone and I think you can see in the video that the wildlife was largely indifferent to it. That was not the case when I walked the boardwalk and trail as many of the birds departed as I approached -- particularly a couple Black Necked Stilts. The drone was, therefore, less impactful than I was. However, I do want to reinforce the need for drone pilots to avoid bothering wildlife.
