This means you're past Round Mountain, which some veterans consider the toughest stretch of trail on the whole race under some conditions. After Round Mountain you're only a couple of miles from the checkpoint. The trail works up the wooded Squaw Creek ravine for a mile or so and then comes out onto the open brushy plateau at the end of the Rainy Pass Lodge runway. Soon you'll pull up onto the runway and then turn left onto Puntilla Lake. The checkpoint is on the lake just ahead.
Water is available from a hole in the lake ice.
You can rest in the checkers' cabin. If you're there during the day, you might be able to buy a meal in the lodge if it's open.
