If you would like to get a better idea of our simulation before you install it on your computer, click HERE to download a14.4 MB wmv video file that shows a "bat's eye view" of the area both outside & inside the cave just past the Bat Gate (designed to keep humans out of the cave while the bats are in hibernation). Look for another link at the bottom of this page for a longer video. Depending on the speed of your Internet connection, now might be a good time to go for that cup of coffee while the wmv file makes its way to your computer. A longer video is in the simulation.
On September 1, 2001, when Snowy River was discovered, this was the area that was first seen by the members of the dig team consisting of Lloyd Swartz, John McLean, Don Becker, and Andrew Grieco. If you were a tiny bug on the far eastern wall with a very bright light this is what you may have seen. Pictured in this July 12, 2013, blending of photographs is a panorama looking at the west wall in the center. Three of the four members of the Caver Quest photo team are shown in this photo: left-to-right are Rob Wood, Ron Lipinski and Wayne Walker. The darkness behind Rob is where Snowy River heads south for another 10+ miles. Wayne, in the green shirt, is standing in the joint-controlled passage that leads back to the Priority 7 dig through crawls and tight spots.

The original explorers marked the pristine clay floor with orange plastic tape to guide future visitors along the unique path. Before exploration could begin an environmental impact statement was prepared by Mike Bilbo, our BLM Cave Specialist. Two years later the first team to actually step on the white crystal surface at first tried special footwear. Quickly realizing that the surface was not quite as delicate as first believed, the teams developed other techniques to protect the surface. Behind this view Snowy River winds around a large boulder and almost immediately the ceiling drops down to within a few inches of the surface of the white calcite floor. The black manganese coating on the ceiling is typical of much of Snowy River where the microbiological forces are at work slowly eating the limestone layers.

During 2010, physical Research and Exploration of the Snowy River Passage came to a halt due to a significant snow and rainfall event which caused the stream to flow from April 22, 2010, to December 21, 2010. This was at least the second "flood" event that occurred during the "normal" science and research season since discovery of Snowy River passage. After the original discovery the passage was explored both North (to Crystal Spring) and South just past Turtle Junction, at which point the Priority 7 discovery passage was closed for safety reasons. Several years were spent locating and digging a new access shaft from Don Sawyer Memorial Hall down to the Mud Turtle passage that again allowed the research and exploration to continue. Scientists discovered many new features of the unique Snowy River Passage and with easier and safer access, it became obvious that it was key that this important work should continue at an accelerated pace. It was also obvious that such an important resource, now the central focus of a new National Conservation Area (NCA), should be protected from surface pollution at all costs and that Research and Exploration should be emphasized during the six months when access to the cave is allowed.

As the exploration of Snowy River pushed South, additional detail survey data was obtained and at the same time photographs of the unique features of the passage were recorded. The exploration teams developed special techniques for traversing the extensive passage (currently over eleven miles in length) following the white crystal-floored passage. Scientists often followed on the very next trip to more carefully record the new data and make specialized measurements. The geology and hydrology of the passage was studied and core samples started to reveal the age of the formation. Sediments were studied to develop a better idea of the time-line of the passage formation. DNA samples were carefully taken and are currently being analyzed.

So, during 2010, the Caver Quest project headed by Dr. Ron Lipinski was formulated to facilitate improved efficiency of the science teams, provide a tool that the BLM could use for better management of the resource.

Currently Fort Stanton Cave is over 64 Km long and is the second longest cave in New Mexico, just before Carlsbad Cavern. (A password is no longer required for the download.) Starting with the July, 2013, Version 6, Caver Quest is using a new Unity Player engine that allows PC, Mac and Linux installations.

Dr. Lipinski began by using the game engine for URU (with gracious permission from Cyan, Inc.), which is an immersive game that begins with an avatar entering a cave in New Mexico. He has since switched to the Unity3D game engine for greater versatility and multi-platform compatibility. First loading in the precision survey data from the program COMPASS, Ron constructed a 3-D framework of the cave passage in and around the areas between the Priority 7 Junction and Turtle Junction. After applying the wall, ceiling and floor distances from the survey notes, Ron applied a generic "wallpaper" obtained from previously archived FSCSP photos from the survey and exploration teams. Since this technique did not show any of the actual photos at a particular spot in the cave, it was proposed to use actual photographs taken every 10 feet along the passage being enhanced. During the April, 2011, expedition the FSCSP was given permission to experiment with new photography techniques using a wide angle lens on a digital camera mounted on a compact panorama tripod head. Over 900 images were taken between survey stations SRS11 and SRS32 using multiple strobes for each image. The 4-person team, led by Pete Lindsley, took careful notes locating each photo relative to the existing survey stations, and multiple shots were taken in some locations to improve the lighting. The resulting collection of images were grouped into sections along the survey line and were next blended into larger images such as the image on the right which shows the Turtle Junction area between SRS23 and SRS25. Just above the white floor of Snowy River is the west wall and some of the black plastic used for the changing area and the trail leading down to Snowy River. The ceiling runs across the middle of the picture, with the (up side down) east wall just above. The east edge of Snowy River runs across the top. The lighting has been adjusted to minimize dark spots, and places where the lens did not fully cover the scene have been filled in using Photo-shop techniques. If you look closely at the edge of Snowy River about 2/3rds across the bottom just below the clay floor line you can see the FSCSP Mini Diver data logger. Clicking on the picture will load a higher resolution photo that shows the red string attached to the data logger. In the actual CQ simulation there is an even higher resolution image that forms the "wallpaper" that the avatar can examine even closer.

using LIDAR data. Made maps in Snowy River now larger. Total length of passages accessible in simulation: 7.65 mi.
Version 6.6.8 & 6.6.9: Total length of passages accessible in simulation = 7.10 mi. Updates Include: In September and October our LIDAR teams were able to access Snowy River again after being flooded for four years. We added all of Snowflake Passage, which has been visited by only a few cavers due to the usual sumped or else very muddy condition of the Sewer Pipe Passage. We also updated the Snowy River passage between the Priority 7 Landing and Independence Hall. The geometry was significantly improved with the new LIDAR survey replacing the previously hand-sketched dimensions from the 2003 Suunto survey.
Version 6.6.7 Updates Include: Added Sewer Pipe Passage (and Gutter Passage). Corrected the slope of Conrad's Branch and the water levels. Added controls to adjust water level in Conrad’s Branch at the Bridal Chamber, Inscription Rock and Sewer Pipe Landing. Reduced color saturation level by 30% in Entrance, Main Corridor, Decoration Passage, and Don Sawyer Memorial Hall. Total length of passages accessible in simulation: 6.51 mi.

Version 6.6.2 Updates Include: Added Hell Hole for your healthy knees. (1700 feet of mostly crawl passage off of the Lunch Room in Decoration Passage).(Bug Fix: Updated menu buttons so they stay at bottom of screen. They used to be too high when the screen width to height ratio was less than 1.53.)
Version 6.6.0 Updates Included: Hell of a Thousand Pinches and Russell's Crawl have been improved can be entered. Don Sawyer Memorial Hall (DSMH), Roaring Hill, and Promise Passage have been added. The Snowy River Wall Map at Turtle Junction has been updated to Oct 2014.
Version 6.5.4 Updates Included: We added coarse renditions of previously omitted portions of the historic cave (Bat Cave, Hell Hole 2, Hell of 1000 Pinches, Russell's Crawl, Conrad's Branch, Sewer Pipe, Snowflake, Snowflake 3, and Priority 7. These are visible during the intro video. Extended the intro video bat flight through Crystal Crawl to the Lake Room and then back through hyperspace to the Circle Room. Added more music clips to the intro video for variety. Added a button to turn of passage labels in the intro video. †he introduction video will loop continuously until the "Skip Intro" button is clicked.
Version 6.5.2 Updates Included: We added Decoration Passage as a new section of the simulation and moved Crystal Crawl into the new section. Next we added the passage from the end of Crystal Crawl to the Lake Room overlook, based on recent Lidar scans and some new wall photography. Look closely and you will find the Lunch Room, Crooked Thumb Passage, Rose Bowl Room, Binocular Crawl, Our Latest Crawl, Pool Finger Room, and Lake Room using the Lidar data and photos from the October 2016 expedition. The Rose Bowl Room, Lunch Room, Pool Finger Room, and Lake Room use local wall photos for texture; the rest is generic wall paper. We also added a new map (two pages) for Decoration Passage, and added juniper trees at the entrance and a pause button for the intro Fly-by video.
Previously we added Snowy River North and South to Crawl from Hell to the introduction flyover (but not the fly through). Just so you can briefly experience the Crawl From Hell, we added a short crawl section at the start. Recently we added pop-up messages identifying major rooms and passages as you enter them. The Turtle Junction tarp cave note now has a voice. We improved the quality of the texture mapping in many places from the Entrance to the Lake Room. The New Mexico cave law was added to the cave note at Crystal Crawl and Pool Fingers.
