Upper Falls

The upper falls are about 60 meters wide and 15 meters high. At peak volume, their discharge is second only to Niagara Falls among free-falling waterfalls east of the Mississippi. Admittedly, it's a distant second.

The falls flow over late Precambrian sandstone.

Below are views of the upper falls, At high water (first four pictures) there is a continuous fall all the way across, but here at lower discharge the falls split.

Lower Falls

Lower tahquamenonfalls is a series of cascades and small falls with the highest about 3 meters high. The river divides around a small island. Below is the west channel. The only access to the island is via rental boat or wading.

Left: Map of the lower falls area. The river here actually flows north around a small island. The west (left) channel is accessible by trail; the east (right) channel is accessible only from the island, which can be reached by rental boat or wading.
Left: falls in the west channel with view platform. The trail extends beyond the view platform all the way to the upper falls.
Left and below: The main falls on the west channel. The trail follows the north bank of the river. This channel carries the most water, so even at low water, access to the island requires wading.
