Georgetown rode the crest of the silver boom during the second half of the 19th century. Most of the impeccably maintained brick buildings that make up the town's historic district date from that period. Georgetown hasn't been tarted up, so it provides a true sense of what living was like in those rough-and-tumble times. It's a popular tourist stop in the summertime. Be sure to keep an eye out for the state's largest herd of rare bighorn sheep that often grazes alongside I–70 in this region.
