Accessed the Swift Trail after about 1/2 mile on Rainbow Trail. Rainbow Trail mostly dry, Swift trail is mostly snow covered. Trail has a great pack all the way to the lower Lake of the Clouds. From there we booted through 6-12 inches of snow (a few deeper postholes where snow had drifted around some rock sections), to the ridge. With 4 of us we put in a bit of a booter, although maybe not the most direct line as we weaved around some, and also went up and over a couple minor rock obstacles. None of us used snowshoes or traction, although some folks would probably like spikes. Almost completely bare from ridge to summit.
