I thought this trail-less destination looked promising on the map; a cozy isolated tarn in seemingly expansive subalpine meadow with views toward the Monte Cristo group. Well, not so much.
The Boulder Lake trail is within DNR lands outside of Sultan. It is quite brushy and rutted for the first 2 miles with a couple of troublesome blowdowns. The last 2 miles are in Old Growth forest with fine tread. I departed the trail at the lake outlet to attain the east ridge. It was a strenuous thrash, but fully expected. Instead of finding subalpine meadow I saw more cedar scrub and thick blueberry brush under dense tree cover. The only grateful patch of open space was immediately surrounding the tarn just below ridgeline, no views other than trees.
Within an hour of reluctantly setting up camp the plague of insects descended. It was apalling, shifts of black flies, gnats, and mosquitos took turns at bloodletting; gnats and blackflies ignored my 95% DEET.
I was grateful for the diversion of a black bear in the evening. My ever vigilant dog alerted me to its unseen presence with her usual polite ""woof"". Thirty seconds later I saw the brush rustle at the near edge of our little meadow, a large buck black bear popped out. It saw us, turned and dove back into the scrub, bumbled around the tarn basin and finally left, peaceable enough. My dog always reminds me how dim many of my senses are.
Needless to say I packed and bolted the next morning. This is a fine destination only for those thirsting for the feeling of isolation, otherwise there are dozens of better destinations throughout the Cascades.
