Question: How tall is the mountain that is south of the canyon? Passage:Granite Canyon is located in Grand Teton National Park, in the U. S. state of Wyoming. The canyon was formed by glaciers which retreated at the end of the last glacial maximum approximately 15,000 years ago, leaving behind a U-shaped valley. The canyon lies between Rendezvous Mountain to the south and Mount Hunt to the north. The trailhead for the canyon is on the Moose–Wilson Road about north of Teton Village. One of the most popular hikes from the trailhead is to Marion Lake by way of the Granite Canyon Trail which traverses the length of the canyon.

question:
Question: What was the name of Yes first two albums? Passage:Hot on the heels of the huge success of CSNY and Led Zeppelin, British band Yes rapidly established themselves as one of the leading groups in the burgeoning progressive rock genre, and their success also played a significant part in establishing the primacy of the long-playing album as the major sales format for rock music in the 1970s. After several lineup changes during 1969–70, the band settled into its "classic" incarnation, with guitarist Steve Howe and keyboard player Rick Wakeman, who both joined during 1971. Although the extended length of much of their material made it somewhat difficult to promote the band with single releases, their live prowess gained them an avid following and their albums were hugely successful – their third LP The Yes Album (1971), which featured the debut of new guitarist Steve Howe, became their first big hit, reaching #4 in the UK and just scraping onto the chart in the US at #40. From this point, and notwithstanding the impact of the punk/new wave movement in the late 1970s, the band enjoyed an extraordinary run of success—beginning with their fourth album Fragile, each of the eleven albums they released between 1971 and 1991 (including the lavishly packaged live triple-album Yessongs) made the Top 20 in the US and the UK, and the double-LP Tales of Topographic Oceans (1973) and Going For The One (1977) both reached #1 in the UK.
