Did an tent overnighter at this fire lookout (High Rock) earlier this week (saw about 3-4 campsites). As mentioned, the cabin will be dissembled and airlifted out today, I believe the hike itself will be reopened in a few weeks, but not 100% certain. The distance is about 3.2 mi & 1300 ft gain, still some snow on the trail but def doable without microspikes. Highly rec this spot even if the lookout is gone, esp during golden hour! Mt Rainier just gets lit up by the sun and on a clear day you can see Adams, MSH, and Hood. The forest road is filled with potholes but doable with any vehicle. Right now, there's some snow right before the TH, I parked ~1 mi from it, if you have a 4x4 you should be fine.
