10/366: Blue Hole New Mexico
On our way out to Colorado we visited the Blue Hole in New Mexico. What is the Blue Hole?
The Blue Hole of Santa Rosa is a circular, bell-shaped pool east of Santa Rosa, New Mexico that is one of the most popular dive destinations in the US for SCUBA diving and training. The Blue Hole is an artesian well that was once used as a fish hatchery. It is a clear blue body of water with a constant 64 °F (18 °C) temperature and constant inflow of 3000 gallons per minute. While the surface is only 80 feet (24 m) in diameter, it expands to a diameter of 130 feet (40 m) at the bottom.
Since Santa Rosa, New Mexico is at an elevation of 4,616 feet, it is necessary for divers to use high-altitude dive tables to compute the dive profile and decompression stops when diving in the Blue Hole.
