Notes:

• Damaged by fallen tree, summer 2003. Soon repaired. Destroyed during storm, October 2003. According to a June 2004 National Park Service web page advising as to storm damage in North Cascade National Park: "The suspension bridge over Thunder Creek one-mile from the trailhead in Colonial Creek Campground was destroyed. This large bridge was in a location which flooded at the beginning of many summer seasons. Planning for a better location, environmental assessment of alternatives, and application for funding will take place this year with construction happening in 2005. The log jam at the former bridge site is closed to crossing because of safety considerations." The bridge was indeed replaced with a non-suspension bridge at a different location.
