PEEC Nature Center free public event, Los Alamos, NM

We had several hundred people enjoy CaveSim at this free event at PEEC.  The event was sponsored by Classic Air Medical, who landed one of their helicopters next to the CaveSim trailer.

We love teaching, and kids love learning (when you make it fun!)  Dave says, “One thousand years per cubic inch for this formation to grow!” Photo by Thomas Graves.

National Speleological Society Convention, Rio Rancho, NM

Such a great 5-day Convention!  The kids who attended got to do incredible CaveSim electronics labs.

Students soak up a lesson on electronics (based around our cave rescue phones).  The lesson included first-hand experience with time domain and frequency domain relationships and visualization. Photo by Jackson Fulcher.

Our awesome 2017 Convention sponsors include:

USFS Southwestern Region

Mesilla Valley Grotto       Bill Stringfellow


Get Outdoors Day, Denver, CO

A big thanks to the US Forest Service for bringing CaveSim to this fun event for the first time!  We were told that CaveSim was “the biggest hit of the event.”

Atlas Preparatory School summer program

This was our second year working with these great students, and they had an incredible time doing a cool electronics lab during this two-day program — they learned soldering, basic circuits, product design, and much more to create their waterproof flashlights.

US Air Force Academy, Falcon Trail Youth Center, CO

We were honored to be invited back to the Academy for the third time!  As always, the kids loved the cave, but they also loved our new rappelling and ascending tower.  Here are some pictures that parents shared with us:


Natalie and her little sister both loved the cave.  Natalie’s shirt sums up why we do so many cave conservation education events: “The Future is us!”  Natalie also got to try the Frog System.  She said that she’s afraid of heights, but she had no trouble going to the top of the 12′ tower.

Science Museum Oklahoma, Oklahoma City

Visitors loved this awesome free event at SMO from 9AM-6PM!  Thank you to SMO for making this event possible.

Grove School District programs, Grove OK

This was our second year doing programs for students in the Grove Public School District.  This year, we expanded our program beyond Elementary School and we worked with older students as well.  A huge thanks to caver and teacher Deitra Biely for making this 5-day program happen!

During the lab at Grove High School, a student asked his teacher, “Why can’t we do this kind of thing in biology class?” to which Dave replied, “This IS biology class!”  Student: “Oh, right!”  Photo by Tracy Jackson.

Legacy Academy, Elizabeth CO

About 54 fifth graders had an incredible time learning all about caves, science, engineering, teamwork, and more at six different stations during this four-hour program.  We had incredible help from five parent volunteers and two CaveSim educators (great job teaching geology, Tracy and Paul!)

Big Cool Science Festival, Colorado College

Colorado College is Tracy’s alma mater and the site of our first CaveSim school program back in 2010.  We had great turnout and awesome weather for this fun free public event.

Spring Break Camp, CaveSim at CityROCK

We had strong turnout for the 5-day Spring Break Vertical Caving Camp in the CaveSim system at CityROCK Climbing Gym in Colorado Springs.  The Colorado Springs Gazette newspaper came and took some great pictures of our participants learning to ascend in the 40′ vertical cave.

Lake George Charter School Science Night

In addition to bringing CaveSim to this school-wide event, Dave was the keynote speaker and spoke from personal experience about caves, science, engineering, and cave rescue.  CaveSim was hugely popular, with families staying beyond the end of the event so that they could try exploring the cave.

Students adjust the squeezebox, which teaches measurement science and shows the students their personal limits (it’s like the limbo, but for caving!)

Patriot Elementary School STEM Night

We had fantastic turnout at this great Patriot Elementary School STEM event for the second year in a row!  Even the teachers and staff had fun:

The Colorado Springs School, Spring Hackathon Seminar

What an incredible program! Students in grades 6-8 learned basic circuits, programmed microcontrollers, and built cave-proof electronics projects. They got to test their projects in a giant bucket of muddy cave water, and then bring the projects down to CityROCK to try them in the CaveSim system there.  Not only that, but each student got to rappel into the cave, and everyone got a behind-the-scenes tour of the system and the associated electronics.

Please buy from our generous NEW sponsor

Because cavers love a nice warm tub, and every tub needs a replacement cover at some point!  The Cover Guy has everything you need for your tub: hot tub covers, lifters, hot tub filters, chemicals, and accessories.  Plus, they have a great blog.

Kartchner Caverns Cave Fest

We had great turnout for our third visit to Kartchner Caverns in Arizona.  Check out our event flier to see all of the activities we did over a 2-day period.  A huge thank-you to cavers Teresa and Hanna for helping.

Winter Break Caving Camp at The Cave at CityROCK Climbing Center

Campers ages 8-16 learned rappelling and ascending in our CaveSim system at CityROCK climbing gym. The campers made the most of their winter break, and had a great time — our quote of the week: “Mom, this was the best camp ever. I want to come back and do it again,” James, age 8.

On June 25th, 2016 we opened this amazing new cave to the public. Come explore over 225′ of highly realistic water-carved passage, including a 40′ rappel / ascent. Try not to bump into any of the 50+ beautiful cave formations, and compete with friends using the computer system.  More cave passage coming soon!

Carson Middle School STEM Night

Many middle school students explored CaveSim (some as many as 7 times!) despite freezing temperatures and snow (this was definitely our coldest program on record).  A big thanks to Lydia and James for helping us with this event, which ran from 4-6PM.
