The bottom of Lake Falls
Matthiessen State Park
On a hot day at Matthiessen State Park near Utica, Illinois, it's worth the trip down to the bottom of the canyon. Not only for the beautiful view of the stream, sandstone cliffs and waterfalls, but it's much cooler at the bottom. If you get near the falls, the falling water creates a breeze that carries a cool spray of water.
Worth the trip - even if it's cool outside.
