Dillon Ranger District makes little sense, here is what they say...
5.4 miles one-way to summit
Starts at 9,314 feet and ends at 11,123 feet
Continue on the road past the gate and begin to climb along the north side of Straight Creek. The trail parallels I-70 the entire way up to the Eisenhower Tunnel. The trail, an old double-track road, will cross Straight Creek a few times as you climb gradually up the valley through a lodge pole pine forest. Straight Creek runs down from the Continental Divide at the Eisenhower Tunnel along I-70 and into the Blue River in Silverthorne. It is the main water supply for the town of Dillon.

Gate Policy: If a gate is closed upon arrival, leave it closed after you go through. If it is open, leave it open. Leaving a closed gate open may put cattle in danger. Closing an open gate may cut them off from water. Please be respectful, leave gates as found.
