Dry winters are taking their toll on the Great Salt Lake, which is just a couple feet away from reaching its record low level, set over 50 years ago.

Is the level of Great Salt Lake headed for an all-time low?
Is that coral in Great Salt Lake? Great Salt Lake was lower than average last summer, exposing coral-like structures that are usually beneath water. Maybe some of you saw them!
Great Salt Lake has reef-like structures that resemble coral and are often called coral, yet they are not true coral. Algae build bulbous sedimentary rock structures known by various names: algal bioherms and stromatolites are two of the most common.

Great Salt Lake occupies a large basin formed by horizontal stretching of the Earth’s crust across the region. This stretching produces movement on faults, resulting in uplift of mountain ranges adjacent to the
basins and occasional magnitude 6.5–7.5 earthquakes.
A stunning Utah view.

Storm clouds clear over Bridger Bay and Antelope Island, the largest island in Great Salt Lake. Much of the island, including Stringham Peak (left background; elevation 6,345 feet), is made up of Precambrian-age rocks that are some of the oldest rocks in Utah (600 million to 2.5 billion years old).

Urban geologic mapping may sound like a mapping geologist’s nightmare with all the private property, disturbed land, and development rapidly covering up the geology. Despite these difficulties, my experience with it has been exciting and challenging. Why map geology in and near the city? The simple answer is that urban areas need surficial geologic maps to aid in geologic-hazard identification and mitigation. Additionally, a good geologic map provides the basic geologic information needed for further geologic, groundwater, geotechnical, and engineering investigations.

Great Salt Lake • A salt-laden November fog fills the valleys of the Promontory Mountains like the crests of waves on an ocean. Thick storm clouds allow scattered streaks of sunlight, creating sliding silver bands on a water tinted red with bacteria.
