The trail to Upper Lena is clear of blowdown except for one large root wad just below the lake basin. On Fri. the lake basin was very foggy, temporarily dashing my hopes for good viewing of the Perseid meteor shower. The fog cleared in the wee hours of Sat. morning, exposing not only the meteor shower but also a nice display of northern lights. It got plenty cold and a thick layer of frost covered the ground next to the lake on Sat. morning. My thermometer registered 26 degrees, but fortunately the sun came out and it got warm rather quickly. I day hiked to Scout Lake to scope out some potential traverses to L. of the Angel and/or Hagen Lake. The Scout Lake way trail was very brushy near Upper Lena, but became much more open once it climbed into the heather and huckleberry fields. Excellent views. A few small snow patches still lingered, but were no problem. I had trouble finding the supposed route to L. of the Angels, as described in Wood's book, but the route to Hagen looked intriging. I returned to FR 25 on a knee crunching descent just as teeming hordes of backpackers were invading Upper Lena from the lower lake.
