My wife and I and our friend Stan were looking for a lowland hike somewhere up the North Cascades Highway. We decided to start out with Thunder Knob at the Colonial Creek Campground. This is a fine trail, except at the very beginning, and still in the campground, which requires delicate stepping across some braided creeks. Normally a bridge is in place but that has been temporarily removed for the Winter. Also, there were a number of blowdowns along the trail, but were navigable with minimal effort.
This trail climbs moderately, about 650 feet in a mile or mile and a half, to about 1900 feet elevation. We had lunch at the top, with views of Diablo Lake and then returned to our car.
Looking for more adventure we decided to stop at Newhalem and visit Ladder Creek Falls, a short hike right near the Gorge power station. These are some beautiful falls, and are lighted in the evening hours.
Returning once again we noticed a footbridge crossing the river to the "Trail of the Cedars." This is an easy loop trail, built by City Light and the University of Washington Forestry department, and has informational signs about the environment. However, it is also possible to follow a spur trail to the Rock Shelter, a large boulder near Newhalem Creek, which Native Americans used for a hunting (Mountain Goats) and fishing shelter for about 1200 years. Smoke stain from their fires is still visible on the walls, but it is illegal to actually enter the shelter. There is a (nice) wooden platform from which you can view the shelter.
The trail to the shelter has a spur which we decided to follow and it led to a couple of spots along Newhalem Creek adjacent to the river. Here we were able to do some photography, in my case some hand-held (with assistance from logs and boulders) time-lapse photos.
All in all a very pleasurable day.
