The trail continues past the Loch, crossing Andrews Creek and meeting the spur trail to Andrews Tarn. Stay on the main trail as it bends south. When the trail exits the trees it gets quite steep, ascending numerous stone steps to Timberline Falls. A few yards west of the falls, the trail ascends a steep broken cliff and is often wet with falling water. From the top of the falls, Glass Lake is just a few more steps.
