Flush Gap Map

Think of Flush Gap like a toilet bowl - constantly flushing. Getting caught in an avalanche here could be disastrous. It starts out near the ridge below Morning Glory Bowl much like the surrounding terrain; mainly open with some trees interspersed. Flush Gap quickly changes. Below a tree island, the slope opens and steepens dramatically. A ridge runs vertically down the right side. This can make for a fun spine line, but below another tree island on the right, which houses a cable used for avalanche control, the slope drops away here 40 feet to the slope below. The center of the gully is straightforward, not requiring a cliff-drop. However, even a small slough could knock you off your feet. The left side of the gully is more face-like, but as it enters a tree band, it, too drops over a cliff with a rocky apron below. Regardless of your line, watch for avalanche debris below this cliff band and/or gully funnel. There will undoubtedly be frozen chunks to navigate. Note that once through the gates to Northway, cliffs and other hazards are not marked. This is avalanche prone terrain. Carry the proper equipment and ski/ride with a partner.



Steep skiing at 38-45 degrees. This requires very good technique and the risk of falling has serious consequences.
