July 20th

Sunday. Weather continues fair. After our Bible reading Morse, Adams, McBride and I, started to put out flags from W side. We went today in order to take advantage of the good weather and to be able to measure motion before the other flags should fall. We started nearer the front of the glacier and nearly succeeded in crossing; we put out six flags (6' x 4.5') the furthest being quite near the last from the other side. The last part of the passage was very difficult, and for three hours nearly every step had to be cut; [the?] crevasse was immense, the wedges of ice high and steep, requiring careful climbing to pass in safety. We turned at 7 pm. The large pinnacles showed the stratification and at the same time the new striae cutting each other at an angle of ab. 65 degrees exceedingly well. We returned to camp about 10 pm. Well pleased with our success. The flags now practically extend across the glacier, within about 1/4 mile from the port.
