Our presentation this month will be by Ryan Braga
Central Ohio is not typically regarded as prime karst territory, yet the Scioto River corridor harbors a collection of caves carved into the region's limestone. Among them, Courtesy Cave stands out — both in passage development and the exploration it inspired. This presentation covers the history of exploration at Courtesy Cave, from fragmented early accounts to methodical modern survey, and places it in the context of the broader cave systems along the Scioto corridor that collectively speak to the karst potential of a region often overlooked by the caving community.

Benefits of volunteering: -Hang out with other cavers -Learn new caves and passages -Earn services hours for school, etc. -GSP camping dues are waived for the weekend you volunteer. Once you sign up you'll be sent an email, leading up to the trip, with detailed information about that weekend.

Join us March 27–29 for a Spring Warm-Up Caving Weekend! This trip is designed as both an introduction to caving and a great way for experienced cavers to kick off the season. Whether it’s your very first time underground or you’ve been caving for years, this weekend will have something for you.
We’ll be camping Friday and Saturday night at the Great Saltpetre Cave Preserve, which gives us access to a great setting to spend the weekend together. On both Saturday and Sunday, we’ll have cave trips that are beginner-friendly and ideal for someone’s first cave experience, while still being enjoyable for more experienced cavers looking to shake off the winter rust.
This is also a fantastic opportunity for anyone interested in becoming a grotto member. If you’ve been curious about getting involved, this would make a perfect first trip to meet people, learn the basics, and see what it’s all about in a welcoming and supportive environment.
We’ll also visit the historic show cave at Great Saltpetre Cave, a registered historical landmark that is only open to the public two days a year. It’s a rare chance to experience an important piece of history that most people don’t get to see.
If you’ve been thinking about trying caving, this is a great place to start. And if you’re already experienced, it’s a perfect way to start the spring season with good people and good trips. I understand there will be questions, and I’m happy to answer anything — just comment on the event or send me a message. Looking forward to a great weekend underground!
