Tourists, explorers and adventure enthusiasts are always looking for new destinations to discover. Be it parks, hills, rocks, lakes, beaches, rivers or high peaks, the U.S. has an abundance of natural wonders that attract millions of tourists each year. Blue Hole New Mexico is truly a marvel: a clear blue swimming hole, about 60 feet wide and 90 feet deep.

It is a complex network of underwater caves, right in the desert. And not just that, this popular diving destination is located at an elevation of over 6000 feet and has a constant supply of water. Situated about 115 miles east of Albuquerque, the Santa Rosa Blue Hole New Mexico is considered one of the best open water diving spots in the Southwest. Once known as the Blue Lake, it is one of seven sister lakes that are connected and fed by the same underground water system.

What Is Blue Hole New Mexico?

The Santa Rosa Blue Hole New Mexico is located off Route 66 and is a swimming and diving spot open to all. A sinkhole in New Mexico’s arid climate, it is an extravagant natural formation. It has been unexplored for many years and it is only in the past decade that exploration teams have dived deep in to it to discover what lies beneath.

How It Was Formed

This striking blue water hole was formed when the surrounding area’s limestone bedrock collapsed and filled an artesian (denoting constant water supply without any pumping systems) well that pumps out 3000 gallons of water per minute! That is equivalent to filling three Olympic size swimming pools every three hours. The water in the sinkhole comes from the Ogallala aquifer.

The sinkhole has new water in it every few hours. This prevents the formation of algae that grows in stagnant waters, contributing to the crystal clear waters and great visibility. The artesian spring that provides constant water to the sinkhole was formed due to the collapse of geological layers and consistent water action.

Blue Hole was apparently formed about 20,000 to 100,000 years ago. Sink holes or cenote lakes (as they are also called) are formed due to water erosion below and water pressure from springs above resulting in this geological phenomenon.

The Santa Rosa sink was formed due to water seepage and erosion for thousands of years, resulting in a large basin.

Blue Hole has an extensive network of underwater caves that probably connect to other caves and lakes. Some believe the cave system under the Blue Hole could extend up to Carlsbad Caverns, almost 200 miles south of Santa Rosa or even up to the Gulf of Mexico That would make Blue Hole a part of the world’s largest cave system. Blue Hole New Mexico is one amongst many other lakes in Santa Rosa that feed the Pecos River.

Past Explorations

In 1976, two student divers from Oklahoma State University managed to enter a narrow opening of one of the Hole’s chambers. They reached a depth of more than 100 feet but silt displaced due to their movements, obscured the cave opening, and they went in the wrong direction. They found no exit and lost their lives. One body was recovered immediately while New Mexico state police needed six weeks to find the body of the second diver.

During the recovery operation, the police also found another entrance to a deeper tunnel that had not been explored before. After this accident, the city of Santa Rosa sealed the entrance to the underwater caves with a grate and the U.S. Army dumped rocks over the grate to ensure that nobody else would be able to access the vast chambers under the sinkhole and risk their life.

It was in 2013 after many years that explorers removed the grate and ventured into the deep sinkhole once more. This project was undertaken by the ADM Exploration Foundation. Their lead explorer was able to access one of the cave chambers that had been untouched since 1976. He even took off all his diving gear to be able to squeeze through the opening, but the entrance to the second room was blocked by a huge boulder; and although several divers tried to shift or dislodge it, it did not budge. Also, they could not go deep and a huge part of the underwater chambers remains undiscovered.

Many teams have worked to remove all the rocks and silt that has been deposited over the cave system entrance to make way for new exploration opportunities and plans. This has increased the supply of freshwater from the artesian well and improved water clarity. It has resulted in better visibility for divers and also the people downstream who consume the water. A new grate built by the Santa Rosa Public Works Department has been installed to cover the exposed cave entrance and avoid any untoward incident for tourists and divers visiting Blue Hole New Mexico.
