Otto Stadial Site

NEEDS ACCESS REVIEW - The stadial site in Otto is a place like no other. Otto is one of only two known places in New York to have preserved till layers from first three glacier movements (of four) during the Pleistocene Ice Age. Here you will find yourself hiking along the bank side and experiencing things that you have never seen before. The till was deposited by the Wisconsin glacial event that occurred about 64,000 years before present to about 12,300 years before present, during the Pleistocene Epoch and covered almost all of New York. Each layer was deposited by a different advancement of the glacier (caused by cooling and warming). These are called stadials and interstadials respectively.

If you aren’t in any hurry you can take a scenic route to the site and see what interesting things you might find. Along the way you will be fascinated by the rock patterns along the creek bottom or other evidence that a glacier activity had occurred several times in New York’s geologic past. These include different colors of each till layer (because they are made up of different types of soils and bedrock sediments), striations on rocks (scratches from the glacier moving over the rocks), compacted masses of till (which means it was not sorted by size of particles), and angular rocks (rocks are rounded when moved by a stream but not when moved by a glacier). Once you have arrived at the stadial site you will be in utter amazement just by seeing the preserved piece of geologic past that lays right before your eyes.

Park at coordinates given. 1) Walk down to the creek on the south side of the parking lot and follow to the left to reach the strata layers. To the right you will find till and other evidence. 2) Head east on the road next to the parking lot until you see the bridge before you. Before you reach the bridge, turn off into the field to the right and head down to the Cattaraugus Creek on the left. The strata will be in front of you.
