Our hiking group found the trail up to Lower Lena Lake in excellent condition. No blowdowns, dry tread, and no snow up to the lake. The lake is mostly ice-covered, with open water at the north end. There's packed snow on the trail along the west lakeshore, but not enough to cause routefinding difficulties. The footlog across Lena Creek is in good condition, so we crossed it to access the north shore & enjoy the views. There's also enough open ground to allow camping at some of the designated sites.
One caution: there's an active logging operation in the lower Hamma Hamma valley, so be prepared to meet logging trucks as you drive to the trailhead. THEM, Olympia.
