One thing that has remained the same over time at the Lewis and Clark Overlook near Tiber Dam is prickly pear, shown here. When Captain Lewis and his men made their first trip up the Marias River he noted, "travel was miserable...great abundance of prickly pear and slippery ground." To avoid the slippery cliffs and the prickly pear, the Corps members often walked in chest deep water in the river.
