The Red Town Trailhead and parking lot at King County’s Cougar Mountain Regional Wildland Park is open to public access following a brief closure to repair a sinkhole.
StoryHikers, trail runners and wildlife enthusiasts can once again access King County’s Cougar Mountain Regional Wildland Park from the Red Town trailhead after crews investigated and repaired a small sinkhole that first appeared in the trailhead parking lot in mid-September.
King County closed the Red Town trailhead Oct. 25 after the sinkhole grew from about 12 inches across to roughly 4 feet across following heavy rainfall.
Because of extensive historic coal-mining activity at Cougar Mountain and throughout the surrounding area, King County partnered with experts from the Office of Surface Mining to determine if the sinkhole was related to past coal-mining work. To help ensure public safety, King County closed the trailhead while the sinkhole was investigated.
Earlier this week, engineers determined that the sinkhole was not related to mining activities and was instead related to poor quality fill. Crews have filled the sinkhole with clean material, clearing the way for the trailhead to reopen to public use.
