At GZ, you will be standing on the third-largest earth fill dam in the country (fifth in the world), Garrison Dam. It was built between 1947 and 1953 to develop the upper Missouri River Basin. Interpretive signs around the overlook park share more info about the dam, lake and the area.
Please enjoy the view here, and feel free to share photos. There's a nice place to have a picnic here as well.
The cache is a micro size container in natural camouflage. Please handle it carefully.
Be aware, no overnight parking is permitted, but the cache is available 24/7.
