When artist Robert Smithson was looking for a location to create his latest earthwork in the late 1960s, he hoped to find a place with red water. He came upon Rozel Point, a remote area in the north arm of Utah’s Great Salt Lake that blooms in pinks and oranges, thanks to an ever-fluctuating community of microbes in the salty waters.

Great Salt Lake’s North Arm is a little salty, even for Great Salt Lake. The Union Pacific railroad causeway is a factor in the build-up of salt crust in the north arm. The Railroad will be starting a bridge-building project to replace a part of the causeway, mitigating some of the water flow issues. Two of our geologists here at the UGS talk about the salt build up and how it’s affected the North Arm.


One of the strangest and most striking places in Utah — an enormous oddity that scientists say was created accidentally by human engineering — is getting a bit of a remodeling job.
