Tolcats Creek and canyon, more commonly known as the popular hiking trail to Mt. Olympus, drains both the north and south peaks. Because it is one of the steeper drainages along the Wasatch Front, its ephemeral waterfalls can be dramatic.
The origin of "Tolcats" is unknown, but miners used the name as early as 1879, with wildly different spellings. No one owns the rights to the water in Tolcats Creek.
