Tucked away in the southwest corner of the Hotel Boulderado lobby is an ornate drinking fountain. "Pure cold water from the Boulder owned Arapahoe Glacier" it proudly reads. Drinking fountains like this one used to be found all over Boulder. In the early 20th century, the city of Boulder purchased a watershed of dammed-up lakes fed by the Arapahoe Glacier. A $200,000 pipeline was installed to bring the "99.996% pure" water into town. The Boulderado's drinking fountain is the only one left today.
