One of my top 5 hikes in my 14 years...Hiking up through the fog (and amazing rime ice) into the 54 degree sunshine!

All the pics can be seen here:

I intentionally took this hike, knowing full well it would take me above the inversion. Checking the latest sounding from Salem (http://weather.uwyo.edu/cgi-bin/soundin ... STNM=72694)

I saw the inversion was approximately 2,000'. That means Hamilton's 2,400' summit would stick above it, and I could bask in the sun and warm temps.

Being a weather geek, I took a thermometer and tracked the temps.

The trail was in great shape with just mud in some places. There was ice starting around the 1,300' level and this continued until the 1,800' level. Then, the trail gave way to soft snow.

So here goes, the elevation, temp, and time, including some pictures as I went.

Wow wow wow! That rates as one of the best TRs I've seen here. You really brought it all together. Outstanding photos. Just outstanding. The temps round it out beautifully. Only thing I missed is when you went -- today?

I'm sick that I've had to be inside. Given your passion for this, do you suppose Saturday will offer anything comparable?

I'm sorry, it was yesterday (Wednesday).

I highly doubt much of the rime will be left, temps were warming as the inversion lowered. In fact, while I was up there, it was like shards of glass (the sound anyway) as the rime broke off. It was heart breaking to see that this beautiful work of art was being destroyed. Today the east wind kicked in and blew out the low clouds. However, the warm temps should remain near the summit.

For the record, in all my trips, in, up and through the gorge, I have NEVER seen fog/low clouds settle in like I did yesterday.

I think the only better hike was at Mt. Rainier when I took a similar hike up through the clouds. I was on a saddle and the low clouds were sloshing back in forth (like water) and occasionally would spill over the saddle, it was amazing.

Very impressive documentation of the inversion. Hard to fathom that only a couple hundred feet of elevation would be 20 degrees difference, and such opposite conditions

Great pictures WC!

I've probably asked this before but what camera are you shooting with? And
did you PS any of those?

Thanks :)

Very cool! Makes me regret that I did not make it to Table Mtn yesterday as planned. :(

I was thinking, as I took my lunchtime walk yesterday, that that was the day to be "out there!" What a fabulous stroke of timing you had there! :)

Ditto on the wow - that first photo really set me back - the transition between cloud and clear is so abrupt. And the travel through the transition - great stuff - a TR for the ages.

Good stuff :D I still remember your Burroughs Mt hike tr you refer to and then I see Mark Nelson showing one of your photos on his weather segment.

Inversions are pretty fun for those who venture out . I was not as good a recorder as you but Sunday It was 33 at the trail head 26 on top very normal for a non inversion day. That 3 degree per thousand feet is pretty accurate under a normal atmosphere.
