Long Description:
These strange formations of hard limestone over soft sandstone weather to form "mushrooms" -- and sometimes the erosion forms a natural arch.

One such arch can be seen along the I-94 as you head west from Forsyth MT.

BE CAUTIOUS getting out of your car here -- I will accept a drive-by photograph because of the narrow shoulder on the westbound I-94. A better parking area exists as you come east on the I-94.
Photo of the Arch by itself?: yes

Type of Arch: Wind Eroded

Type of Material:
These strange formations of hard limestone over soft sandstone weather to form "mushrooms" -- and sometimes the erosion forms a natural arch.
