SOAR Inflatable Canoes - Somewhere On A River

General Description

Black Canyon on the Gunnison River qualifies as a hairboater's paradise. It offers Class IV to V whitewater, steep waterfall drops, high canyon walls, mandatory long portages through poison ivy on goat trails, heavy tick infestations and a mandatory backcountry use permit. I mean, what ELSE could a boater want? This is a run for expert kayakers only! Full cover protective clothing is strongly recommended for the portages through poison ivy, and insect repellant with DEET is a very good item to carry. Campfires are NOT allowed in Black Canyon, so bring along a propane stove or eat cold meals.

Black Canyon is an E-ticket roller coaster ride with a gradient that changes at least 14 times in less than 15 miles. Its steepest segment drops at about 210 fpm, and its "flattest" segment is about 21 fpm over the final 13.4 miles of this run. Flow is dependent upon dam-released water from Crystal Reservoir. The scenery in Black Canyon is awesome, showing the power of water where it cuts through solid rock to create an immense canyon with walls towering above the riverbed. It's a lot of work getting into and running Black Canyon, but for kayakers with the skills and nerve the reward is an experience few will ever share. A Black Canyon run also entails running Gunnison Gorge unless you are willing to climb the chukar trail at the put-in for the gorge with boats and gear to exit the river. (Note: Gunnison Gorge is a Class II to IV run of about 13.4 miles that many expert kayakers find less than challenging.)

Water Quality and Flow Rates

The Gunnison River usually flows clean, clear and cold with a beautiful blue color, though very "white" in many places, but it is not drinkable without purification. Black Canyon is rated Class IV to V at flows of 700 to 3,000 cfs, and at least two difficult portages will be required to survive this run. Drysuits or wetsuits with a base layer, Neoprene gloves and Neoprene hard-soled river boots are recommended to prevent hypothermia if you go swimming.

Best times to go

Black Canyon, because of dam-released water, has a "long" season by Colorado standards, running from May through September. Contact the Black Canyon National Monument Visitor Center (970-249-1915) for water release information.

Hazards to navigation

Almost every part of Black Canyon should be considered hazardous. The first 14.3 miles of the trip is the Black Canyon section, but unless you want to hike UP the Gunny Gorge put-in trail with boats and gear you are in for another 14.3 miles of paddling to the take-out at Gunnison Forks. The first third of the run will be a series of Class IV to V steep drops down to The Narrows, where things start to get hairy. (Hey, you ARE a hairboater, aren't you?) At The Narrows there is a Class V rapid immediately above an 18-foot waterfall below which are rocks that can pin and/or destroy boats, and injure or kill paddlers. On river left are three lines into the drop. The middle line is best, but all three are very hazardous. If you survive the drop, then start your first mandatory portage on river right. Thick poison ivy and a dense tick population await you on this portage of about 2/3 mile up the side toward the south canyon wall, along a cliff, then down a talus slope to the river. Ferry across a pool, then continue portaging along the left side where the river disappears under rocks. Ferry a second pool back to river right then take a trail to Beach Camp, a riverside camping spot just downstream from the portage. Just below Beach Camp is the Class IV to V Closet Rapid below which is the second mandatory portage on river right. From here, you have about 6-7 miles of much easier paddling down to the chukar trail put-in for Gunnison Gorge.

The dangers of running Black Canyon cannot be over-emphasized. Do NOT attempt this run unless you are an expert kayaker with nerves (and balls) of 316 stainless steel, accompanied by a group of equally qualified paddlers. It is probably best to update your will before beginning this run.

Reviewer's comments

For those hell bent on testing their skills in extreme conditions Black Canyon offers a true whitewater hairboat experience. This run should ONLY be made by expert kayakers with advanced swiftwater rescue skills when paddling in groups, preferrably including one or more paddlers who have made the run before. This is another Colorado run where the scenery is awesome, but you will have little time to enjoy it. Relaxation is not part of the agenda on the first half of this trip, and even the second half requires attemtion to potential problems and hazards. If getting there is half the fun, then this place qualifies, in spades. The mandatory portages are not easy, and the combination of poison ivy and ticks only adds to the difficulty.
