By comparison to Powell's First Expedition (1869), the Second Expedition
during September 1871 experienced low water conditions. Although the rapids
during low water were not as fearsome in intensity as during the First Expedition,
the Second Expedition party still had to spend additional time negotiating
the boats through portages around rocks in the river. |
