In 1890 prospector Pete Berry staked the Last Chance copper claim 3,000 feet below Horseshoe Mesa, beginning a 17-year flurry of activity at Grandview Point. For a time the Last Chance Mine thrived because its ore was rich, even winning a World's Fair prize in Chicago in 1893 for being over 70% pure copper. But the high cost of packing ore to the rim and then shipping it away for refining doomed the operation. Berry and his partners sold the mine in 1901, and the new owners continued mining until copper prices plunged in 1907. Though mining on Horseshoe Mesa was short-lived, it had a lasting impact: Grandview became Grand Canyon's most popular tourist area for about 10 years when tourism there was in its infancy, and the Grandview Trail built by Last Chance miners to reach their mines now serves thousands of hikers each year.
