Teig was enjoying this slot canyon in southwest Utah. Willis Creek Slot Canyon is located off Skutumpah Road in Grand Staircase-Escalante National Monument. I enjoyed the shapely walls and delicate colors in the Navajo sandstone as it closed in above me. I also loved peering down rocks that the orange-tinted creek has smoothed over time. The smooth and curvaceous rock walls of the narrows, which have been carved by thousands of years of flash floods. I felt small as the narrow walls tower 100 feet above.
