River Description

The Upper South Boulder Creek is a beautiful section of Colorado Class V that will keep your attention for this section as the chill flat pace of the creek in Pinecliffe is not what awaits you around the corner downstream.

The Upper South Boulder has an uncharacteristic section of water at put-in with a concrete channel piping you straight into the first snaking Class V rapid.

Trainspotting Rapid: Entering this drop from the center and snaking your way left to stay off the sharp and blasted rock from the right wall proves about a 30' drop in as many feet downstream. After Trainspotting, you get a brief chance to collect pieces and parts.  Collect debris on the center right island.

In the area after Trainspotting, be sure that your crew is in good communication and in tight formation with a plan to catch the eddies on the right after the creek entrance on river right.

The run gets remote quickly after the water runs directly into a wall on river left at the Gash.

( P )* Portage river right.

While there, please pay respects to a fellow Colorado legendary boater, Paul Zirkelbach whom lost his life here. Keep your group tight and pay attention.

Do not attempt to run the Gash under any circumstances.

Within one mile of put-in, two Class V rapids with dire consequence keep your attention on the USB.

Keep your eyes open on this run, the Felis Concolor (the mountain lion) calls this turf home.

The run has a few eddies and some must make moves. Go with someone who knows the run your first time.

This not a run for anyone less than a seasoned Class V Colorado hair-boater.

The remainder of the run has more hair and loads of unique features, good beefy ledges and tight twisting Colorado creekin'.

The take out is a long haul across Gross Reservoir. Pray for tailwind.

Expect a busy day on the river, and do not be surprised if somebody looses some gear on this run.

To Get There: The put-in is at Pinecliffe on Highway 72(Coal Creek Canyon). To get to the takeout take Hwy 72 from the metro area, at Crescent Village turn right. Take 77S Road down to the reservoir, and then follow signs to the "Inlet Parking".
