One of the best steep creeks in Oregon if you can catch it with water with waterfalls and boulder gardens.
See the description and photos on Oregon Kayaking.
The Oregon Kayaking moderates says 'the boulder gardens are so steep that pins are inevitable at low water', be careful if flows are under 6'. Refer to the Oregon Kayaking description for specific flow information.
Chasm has been run a few times, but is still considered a dangerous and difficult rapid.
