On Saturday, July 17, 1847, Brigham Young and the main group of pioneers left their camp a mile up Echo Canyon and, because of Brigham's illness, traveled only 2-1/2 miles. Their camp of July 17-18 stood on the east bank of the Weber River. On the afternoon of July 17, four members of the Quorum of Twelve and six other brethren climbed the high, steep Supplication Hills northeast of the camp. After walking about 2 miles to the top of the mountain, they dressed for temple prayer and pleaded to the Lord for President Young and others who were sick in camp, for the saints who were following, and for their own wives and children left behind at Winter Quarters. Before returning, they rolled large rocks down from the mountaintop for amusement, passed a lone conglomerate column called Sentinel Rock about 125 feet high, and also reported seeing other chimney-like rock towers in nearby hollows. On the Sabbath, July 18, meetings were held in Temple Camp, and Brigham Young was washed and anointed for a blessing of health, after which he fell into a deep sleep and awoke feeling much better.
