Bird's eye view of the Great Salt Lake's railroad causeway, where pink hypersaline waters of the north arm meet the blue-green waters of the south arm. The breach in the causeway allows water exchange between the two sides.

A rocky causeway divides the waters of the Great Salt Lake, with distinct color variations visible between the north and south arms.

A soil moisture data logger buried in the ground is a specialized instrument designed to measure and record the moisture content of soil over time. Here's how it generally functions:
