The trek from Lobuche to Gorak Shep followed along the lateral moraine of the Khumbu Glacier. Just before arriving in Gorak we climbed adjacent terminal moraines of the Changri Glacier which joins the Khumbu and crossed a stream of glacier melt.
After lunch and settling in at a tea house in Gorak Shep we climbed nearby Kala Patthar which brought us up to 18,400 ft, our highest elevation for the trip. It took two hours to ascend the mountain but was a fun accomplishment with a reward of outstanding views. Although it was a cloudy day we did get some good glimpses of Mt. Everest and Base Camp. Mt. Pumo Ri also screams into the sky right behind Kala Patthar.
