We met for breakfast at the Gateway to greet at least 20 people who were there caving for the weekend. After a hardy breakfast, and Chris’ usual peanut butter pie, Aaron Moses and Abby Hohn joined Chris Coates and I for a day trip into MDC.
Our first destination was to rebolt and survey the Columbia Canyon connection to the LAC passage from the month before. Aaron went up first and made some redirects and rebelays. Abby and Chris started on finding an existing CC station to tie our survey into. They found one above the watering hole labeled X31. We started from there and designated our survey LAE. The drop into CC totaled 72 feet.
Aaron did an awesome job rebolting the traverse across the tight vertical crack of the connection!
Abby, Chris and I surveyed the very muddy connector room and tied it into the LAC12 station. Aaron left us to retrieve the rest of his rope left in Nebraska Canyon the month before. A handline is needed from LAC12 down the sloppy slope to the bottom of the connector room.
We then met up in the Bison Room for some lunch and to attack our next lead. We continued surveying the crawl that lead into the Bison Room. There was a TON of air flowing down the passage, which was trending northwest, into a pit. Aaron worked again on bolting the pit while the rest of us tied in the LAF survey to LAB1 station. (I know the powers that be on the MCD project like to keep one designation for the day, but with so many leads and so many different passages going all directions; it gets so confusing referencing a certain part of the cave without switching designations. Sorry, but for our sanity, this must be done.)
We dropped and surveyed the pit, which ended up being a 57-foot drop. At the bottom we surveyed the surrounding passages and stopped at a tight crawl where all the air was going in. Aaron named the pit Fasten Your Seatbelts.
Note: The 9.5 mm New England rope used on the connector drop will not last that long if heavily used. It should have a watchful eye on it at all times.
