The trailhead was at the south end of the canyon, right above the Upper Falls. These large rock islets upstream from the Upper Falls are remnants of a lava flow resistant to erosion.
Rapids just above the Upper Falls.
Plenty of water flowing over the rocks just before it...
drops over the 109-foot Upper Falls.
The South Rim Trail was tricky because just at the brink of the Upper Falls viewpoint, above, the trail was closed for maintenance. There are several other viewpoints along the South Rim Drive so we backtracked to the trailhead and drove to a viewpoint further along the Drive - Artist Point Viewpoint.
An intervening viewpoint parking lot for Uncle Toms Trail was closed, so we parked at Artist Point parking area and hiked back to the closed Uncle Toms Trail. Along the way we had this view of the 308-foot Lower Falls.
At the closed parking lot we stopped for our lunch and had this...
terrific view down the Canyon.
After lunch we headed down Uncle Toms Trail which is a steep staircase descending 500-feet to a breathtaking , up close view of Lower Falls.

After hauling ourselves up out of the canyon on the over 300 metal steps, we continued to the Artist Point Viewpoints. This is from the lower viewpoint and...
an upper viewpoint. This is one of the most photographed views in Yellowstone.
The multi-hued rocks of the Canyon below the falls result from the hydro-thermally altered rhyolite (from the volcano eruption) and sediments.
Enjoy these spectacular views of the Canyon as we did this afternoon.
