As the calendar welcomed another year, volunteer cavers at Jewel Cave National Monument realized that 2017 would be a year of great excitement. In what has become an annual tradition, explorers entered the cave on Friday, December 30, 2016 for a four-day trip. The cavers traveled to the recently established Deep Camp on the southwest edge of the known cave. While there, they mapped and surveyed an additional 9,777 feet of new passages. This extended the length of Jewel Cave beyond 185 miles. 
When the team celebrated New Year’s Eve at base camp, no one could have been prepared for finding two new lakes on January 1, 2017. With water being rare and only found in less than 1% of the known cave, the discovery of additional lakes is exciting for the Monument’s future. The lakes were aptly named New Year’s Lake and Bonus Lake.
Superintendent Bonnie Schwartz states, “With the establishment of a third base camp in Jewel Cave, opportunities for discovery are quite literally waiting in the shadows of unexplored leads. With the dedication of specially trained volunteer cavers, more secrets of Jewel Cave will be revealed.”
Chief of Resource Management Mike Wiles comments, “Based on the geology and hydrology of the area, I predict that we’ll be seeing many more lakes to come. No one knows for sure what the new discoveries will reveal, but that’s my educated guess.” During this exploration trip, volunteer cavers also discovered the deepest known point in the cave, measuring 814.3 feet. When measuring cave depth, measurements are taken from the highest point to the lowest in the cave, not necessarily from the surface.
On New Year's Eve, the cavers met back at Deep Camp at midnight for a brief celebration of the new year. While surveying the following day, cavers discovered a 70-foot long, 15-foot wide lake - naming it New Year's Lake. Shortly after this discovery, they also found a smaller 15-foot diameter lake, calling it Bonus Lake.
