My gut reaction to this sign is to hit the gas! (Which is coincidentally what I did.) This was a small pass into the heart of Canyonlands National Park, where all sorts of geological treats were waiting. Sign reads: "Caution: Hazardous Conditions Ahead. Rough, narrow road with loose gravel, steep grades, and blind curves. Do not exceed 15 MPH."
