This is a beautifully detailed, laser engraved and precision cut topographical Map of Great Salt Lake in Utah with the following interesting stats carved into it:
- Surface Area: 1,700 Square Miles (on an average year)
- Record High Water Level: 1986 – 2,300 Square Miles
- Record Low Water Level: 1963 – 937 Square Miles
- Length: 75 Miles
- Width: 28 Miles
- Average Depth: 14 Feet
- Maximum Depth: 33 Feet
Interesting factoid: The lake is a remnant of Lake Bonneville, an ancient, freshwater lake from the last Ice Age. Lake Bonneville was 325 miles long and 135 miles wide and 1,000 feet deep. Nearly 17,000 years ago, Lake Bonneville overflowed at Red Rock Pass in Idaho and a yearlong flood ensued. The lake lost about 375 feet of water. As Lake Bonneville shrank, all of the minerals in it — including salt — concentrated into steadily less water. Every year, 2.2 million tons of salt flows into Great Salt Lake from tributary rivers. This accumulation of minerals and no outlet to the ocean results in a salt lake.
(Not all of this information made it onto the map, we just love to read up on the lakes we design).
