Four intrepid COGS members took a trip up Middle Fork Road/USFS 5620 about 10 miles or so beyond the pavement to Goldmyer Hotspring, where we had the whole place to ourselves.  It was a bumpy trip, mostly on double track until we got to the river crossing over the Middle Fork of the Snoqualmie.

After eating our packed lunches we took a blissful soak;  alternating between the hot pool of the mineral spring and the adjacent cold spring with a waterfall providing the background music.  It is remarkably quiet and restful there with only the sounds of Burntboot Creek Falls (my guess is that it was named for the odor of the hot spring) and the birds.  The weather was ideal for the trip, the road was bare and dry under a partly cloudy sky.  I hope to do this trip again next year -- so if you missed out this time you'll likely have another opportunity.  Otherwise, go on your own sometime it is well worth the bumpy 10 miles to get there.  40-plus mm tires strongly recommended, and suspension of some kind would make the ride easier as well.
