Late September 1983. My buddy DogTired and I stepped out of the car at the Fern L TH in RMNP and began xc-ing toward Forest Canyon which was (and is) trailless. It started raining as soon as we began walking. The rain turned to snow as we made our way over a ridge and down into the canyon proper.
Our goal was Forest L or maybe Arrowhead L at the upper end of the valley, about 5 miles. But the deadfall in the canyon was thick and we were not even half way there as the light began to fail. We changed our target to Raspberry Park, which our 7.5′ topo showed as a clear area.
The map was (and is) out of date. There is no park there, just slightly less dense forest. But it was sufficiently less dense that we could find a spot to pitch our tent, eat dinner in the dark and turn in.
Then the wind came up. I have no idea what the local windspeeds were, but Boulder’s Table Mesa NCAR station recorded its highest gust ever, 186 mph IIRC. Due to the density of the forest, windspeed at tent level was not too bad, maybe 20-30 mph. But all that wind energy being absorbed by the forest was causing a major blowdown event. We could hear trees breaking and crashing every 30s or so. It went on for hours.
We were pretty well trapped. There were no open spaces to move to and retreating back to the TH bushwhacking in the night would have been more dangerous than staying put. All we could do was shut our eyes, cross our fingers and hope for the best.
Somewhat to our surprise, we woke up alive. There were 6 inches of snow on the ground. We decided we had had sufficient adventure and headed back to the car. The forest, needless to say, was a disaster area. But we were alive and unharmed, even though we had no right to be. Funny how life works out that way sometimes.
