Long Description:

South of Lewiston, Idaho in the Tammany Bar area there are private gravel quarries in coarse gravel terraces which were formed by the Bonneville Floods, 17,400 years ago. Capping the gravels are rhythmites of sand and silt from the Missoula Floods.

The coordinates are at a closed road junction which provides a parking spot. Remember the quarries are private property so do not trespass.

The best views are north of the coordinates. There are good views from the Tammany Creek Road but parking is limited.

A little further south at the Hells Gate Habitat Unit trailhead (N 46° 21.407' W 117° 03.064' ) there are closer views of the rhythmites.

Limited additional information is available on the website. Check out the photo near the end of the Bonneville Flood section. There is also a photo on the home page.
