The closure of Mount Si and Little Si trailheads and trails will continue through at least Friday, the state Department of Natural Resources just announced.
On February 15, a single-engine airplane crashed in the Mount Si Natural Resources Conservation Area, which is managed by DNR and is a popular recreation area in eastern King County.
Immediately after the crash, the department closed access to the area to better help teams from the National Transportation Safety Board and other agencies conduct their investigation.
Plans for removal of the wreckage are scheduled to be completed by Friday.
“Depending on weather conditions and how well the removal of the plane wreckage goes, we hope to reopen the area for the weekend,” Doug McClelland, assistant region manager for DNR’s South Puget Sound Region, said in a news release.
