Upcoming events


NEW CXT Toilets to be installed by the Forest Service at Whychus Overlook Loop

During the next two weeks ( July 22-28 ) there will be construction under way related to the installation of new permanent CXT toilets to be located adjacent to the Wychus Overlook parking area. The porta-potty will remain in place until the new installation is complete. The New toilets are projected to be operational by July 28th. STA has been a part of this improvement project with the Forest Service USFS and RPT grants.  STA provided three years of donation of the porta-potty services. This has been greatly appreciated by the public.

On Wednesday, July 24th and Thursday July 25th, the Overlook parking lot and loop trail will be closed to the public. Thank you for your patience, it is going to be a nice improvement to the area.
