August 1st-5th:  The next couple days, the team went through what is known today as Glen Canyon. The team named this canyon for they discovered oak glens along the river. On August 4th the teams passes by the Paria River Mouth then into canyon that resembles that of Cataract Canyon. Rapids and falls are found and taken on by the team. On the 5th of August, Powell enters the Grand Canyon by way of Marble Canyon.

August 9th: After many rapids and falls encounters the canyon keeps exposing new geologic features. The walls are now thought to be 2,500 feet in elevation and composed of mainly marble. Springs and vegetation are soon spotted along the canyon walls.

August 10th-13th: The team makes it to the mouth of the Little Colorado on the 10th and decides to stay a couple days. On Friday the 13th, Major Powell comments on the journey. “We have an unknown distance yet to run, an unknown river to explore. What falls there are, we know not; what rocks beset the channel, we know not; what walls rise over the river, we know not. Ah, well! We may conjecture many things.”  

August 14th-18th: The River is starting to get narrower and the walls on the side are getting higher. The crew starts to enter the Granite Gorge. The rapids are pretty rough so the crew decides to lower the boats down the river by way of ropes, a much safer practice. After a stretch of calm River, they come across a clear stream coming from the canyon walls above. Powell names it the Bright Angel. The food rations are dangerously low and Powell makes the decision to get out of the canyon as soon as possible in fear of his men’s lives and that of his own.

August 19th-25th: Over the next week the crew makes valiant strides in covering much ground. On the first day, the Emma Dean crew is thrown overboard and down the rapids. After some rest the crew makes there way along Granite Gorge where the river meanders more and more throughout the days. Ruins are found alongside the river in a couple spots. Some mornings the crew would cover over 10-20 miles of river. On the 23rd the party passes through the Granite Narrows. The river widens and the water quickens helping the boats move quickly. Most of their food is gone and the crew has to base their diet on coffee rations. On the 25th, Powell and the crew come across extraordinary large volcanic rocks, later to be determined as Lava Falls.

August 26th-29th: On this day the crew finds an Indian garden along the river where they help themselves to a meal of squash. Powell estimates that the crew has been making 35 miles of gain a day over the past couple days. On the 27th the crew finds themselves back within the granite part of the canyon, where they experience more nasty rapids. After a day of rest and planning for the rapids, Captain Howland expresses that the expedition be abandoned. He convinces his younger brother Seneca, and William Dunn to go no further. Powell figures they are 45 miles, as the crow flies, from exiting the canyon. Howland, Seneca, and Dunn depart from the group and are never seen again. Turns out they were killed by Indians over confusion. At the point where the team separated, this is called Separation Rapids.  A plaque is dedicated 75 years later in their honor. On the 29th Powell and his remaining crew exit the canyon around noon at the Grand Wash on the western end of the Grand Canyon.
