 Most of his narrative was given over to a springtime trip to Overlook Mountain and North-South Lake, but on the later day he records that he brought a "natural philosopher" friend along with a barometer and climbed "Round Top", which he believed to be the highest Catskill peak, renaming it Liberty Cap in honor of the political change in his homeland.The companion determined the mountain's summit to be 3,549 feet (1,082 m) above sea level, only about 106 feet (32 m) short of its accepted elevation today.This is the earliest recorded climb of any Catskill High Peak.
