Substantial snowmelt since my scouting trip a week earlier. Trail was only about 30% snow-covered this time out. Led a group of 6 Mountaineers new members on this trail. Based on previous week's scouting, we started counter-clockwise from the Tipsoo Lake trailhead, encountering some patches of snow out to the half-way point. Based on reports from hikers coming from the opposite direction (some in shorts and soaking wet tennis shoes!) although there was still a fair bit of snow on the north and northeast slopes of the loop, it sounded like fully-equipped hikers should have no problems. At that time, boots, gaiters and trekking poles were nice to have on some of the remaining snow patches (there are still some snowbridges over shallow snowmelt streams, and a couple of places where postholing was evident, but not nearly as bad as last week), but at this rate of melt-out I suspect the trail will be almost completely snow-free within a week or two. (The new hikers expressed that they felt more comfortable doing the counter-clockwise route, because they were going downhill rather than uphill over most of the snow that lingered.) Lots of wildflowers (mostly avalanche and glacier lilies, magenta Indian paintbrush coming out on the south and east sides, phlox, first few lupines), heard but did not see grouse, and found only one lingering potential cougar print in the snow. Other hikers had reported seeing mountain goats in the vicinity that day, too. If you go, I'd still recommend wearing boots (for traction on the wet snow, and to cross several small muddy spots and puddles on the trail -- Leave No Trace ethics encourage going directly through rather than skirting around these) and bringing gaiters just in case (to keep the slush out of your boots). If you must hike in tennis shoes, either wait a couple of weeks or be prepared for cold, wet feet! Also, bring your sunscreen; I got a nice sunburn on my neck from the light reflected off the snow! (I was fooled by the cloudy start of the day; with the sun behind the clouds it was cold and windy, but when the sun peeked out occasionally we baked rather quickly, and probably got at least some UV throughout most of the day anyway.)
