6:30am meetup. Pitch dark. 1 stop on the way. At 10am 6 of us + 1 dog in-training started hiking. Obsidian Trail is in a permit-only zone. Camping is limited to 12 person per night. This June, we just had hiking permit. Zone sign is posted at the TH, at the zone boundaries. Met a ranger checking permits. 2 runners who pasted us were given choices to hike back out or a $200 citation per person. The trail is strait forward. At Sister Spring, we followed a use trail south to go up to the plateau where the lake is. At 2pm, we reached the 2 ponds which was the lake in a normal year (or earlier season). Elevation 6700'. All nicer camp sites closer to water were all closed for restoration. Up-close view of North and Mid Sister. At the western cliff, good view to Mt Washington, 3 Fingered Jack and Jefferson (Hood is a bit faint) to the north, and Broken Top to the south.
After setting up my tent, I went off for a walk by myself. Followed a use trail out of the plateau east and up one of the many rock piles towards the Sisters. The trail gets fainter the higher I went, eventually I couldn't see the track anymore. Attained the ridge line at 2 different places for better view of the north.
Back to the camp at 5:45, in time for a very colorful sunset (at 6:30). The sky was lit way past the sun set, and moon rose from behind the mountains, almost full. Took many photos. 
Cooked dinner, watched 4 of them playing cards with flashlight. Got into my tent by 7:30, finished cleanup by 8. Read till 9. Went to sleep by 9:30 and woke up around 2:30am, unable to sleep. Bright moon, some clouds. Not too cold, no shining stars. Windy at times.
Sunday. Nice weather in the morning. We departed shortly after 9am. 2 breaks to delayer and put on rain gear. Back at the car at 11:10, in the mild rain. Late lunch at McMenamin's Treasury in North Salem. Multiple accidents on I-5 causing 1 hour delay.
My companions' GPS readings are ~13 miles, 2900' for this trip. My phone registered 30k steps on Saturday and 13k on Sunday. So I probably did ~4 miles more.
