Trail to Lena Lake was in excellent condition -- snow-free and clear all the way. Reports on the trail to Upper Lena from other hikers, were, however, less favorable. Apparently there is a lot of snow up there, to the extent that it is even resulting in route-finding problems. Lena Lake is still quite high, with the bases of trees and parts of the trail around the lake covered by water. Our plan was to head up The Brothers trail to attempt a summit climb. The trail from Lena is pretty decent, some patchy snow starting soon after leaving the lake, but easy to follow the path. A few blow-downs to navigate around / over as well. This trail up to the Lena Forks campsites is beautiful, following the river all the way up. After the third bridged river crossing, you hit another half-dozen or so nastier blow-downs, which are tiring, but again, navigable. Upon reaching the ridge near the campsite area, we hit solid snow for the rest of the trip. A somewhat dicey section of some exposure above the river is made tough due to the steepness of the snow and a narrow path, but once past this, you are at the campsite area. However, due to snow and the height of the right fork of the river/creek, it is unpassable here, and most people pressed on ahead another 1/4 mile to a flatter open area at the base of a chute and camped there, as did we. Camping is only available on the snow, so bring the four-season tent or bivvy bags! There is a snow bridge across the creek in this area. After crossing the creek, you have to hike back down on the other side to where the ""left"" fork of the creek joins, and then head up through the snow and trees, staying just to the right of the creek on the way up. We had some difficulty finding this route initially, and lost a couple hours bushwhacking and even climbing up the gully from our campsite in hopes of being able to traverse over to the route, all to no avail. Once we finally found the trail, it followed the creek up through snow and brush, ultimately opening up to a big snow gully which we followed up to Lunch Rock. From there, more very steep snow to the summit block, and a rock scramble with some exposure up to the top. WOW! 360 degree veiws! All the major mountains of the Cascades were visible, from Baker, Shuksan, and Glacier Peak in the North to Rainier, St Helens, and Adams in the South. To the East, the whole of the Puget Sound basin -- we could even see the buildings of downtown Seattle through the haze once we spotted the white of the Kingdome. And to the West lay the bulk of the Olympic range. Truly wonderous views, some of the best ever I think. Climb up from Lena Forks (minus time spent ""lost"") was about 4.5 hours. 2 pm and time to head back down. Once past the really steep snowfields, excellent glissading. Back to camp and packed up by 5. Now the long slog out on tired legs. Got back to the car by 8:30, and drove home. Excellent weekend! Ice axes required, rope, and crampons recommended.
