Lake Minatare State Recreation Area in Nebraska. It has a lighthouse.
It doesn’t need a lighthouse. It’s not a very big lake, and it’s in Nebraska! But during the dark days of the depression, it was constructed as a beacon of hope. Built entirely of native stone by the Veterans Conservation Corps, it was completed in 1939 and is now known as the Plains Lighthouse. It doesn’t really have a light at the top. It serves as an observation tower and attraction.
