During January and February of 1998, 1,843.55 feet or 0.34 miles of cave was surveyed and inventoried in Wind Cave on 5 trips, raising the cave from 81.21 miles to 81.56 miles. A total of 104 stations of previously surveyed cave was also inventoried.
Hazel Barton, Evan Anderson & Sean Kramer
Hazel led a 12 hour trip to the Egg Hatchery area, where they surveyed 800.25 feet in 46 stations (Avg. shot 17.3 feet). The last lead they checked was a small crawl with a rock in it. After pushing the rock aside and squeezing through, they entered a virgin passage that opened to 15 x 20 feet. They also inventoried 21 existing stations along the EHB and EHC surveys.
Myk Coughlin, Marc Ohms, Kelly Mathis & Mike Wiles
Myk led a four hour trip to the Spillway area, where they surveyed 136.3 feet in eight stations (Avg. shot 17 feet). They also inventoried 12 stations along the UZ survey, where they discovered a 1951 "Spelunking Tour" ticket and some overlapping survey (between the UZ and the JD surveys).
Jamie Sherer, Kathy Petty, Sandy Kramer & Steve Turner
Jamie led a 10½ hour trip to the Historic Section and inventoried 41 stations along the WC, UK and UJ surveys. While inventorying, they noticed lots of unsurveyed leads along the UJ survey and a couple of pools with heavily dripping.
James Wilson, George Fredricks, Todd Durrum & Steve Lipsher
James led a 14 hour trip to the K survey in the Half Mile Hall area, where they surveyed 165 feet in nine stations (Avg. shot 18.3 feet).
Donald Davis & Stan Allison
Stan led a trip to Calcite Lake to show Donald some unusual features he found on the wall that resembled folia. Donald felt that they were bedrock features instead, probably fossil stromatolites or something related to them.
Donald Davis & Stan Allison
Donald entered the Monument Hall area in the Historic Section of the cave to check on some reported helictite bushes that had been vandalized by Alvin McDonald in the 1890s and are located in a parallel passage 1,000 feet east of the other Wind Cave helictite bushes. Donald determined that although they have the same shape as the others, these grow from boxwork fins projecting from nearly vertical surfaces, instead of out of floor crust.
Sandy Kramer & Jamie Sherer
Sandy led a 11 hour trip to the Historic Section and inventoried 30 stations along the VH, UK and AI surveys. They located some bat scratches and a lot of delicate cave.
Greg Glazner, Jim Wilson & Tim Moreland
Greg led a 12½ hour trip to the Club Room, where they surveyed 266 feet in 20 stations off the PZ survey (Avg. shot 13.3 feet). They found a 20-foot diameter room heavily decorated with frostwork. Jim reportedly scooped extensive passage beyond this room.
Hazel Barton, Evan Anderson & Shawn Kramer
Hazel led a 14½ hour trip to the Club Room section, where they surveyed 476 feet in 41 stations (Avg. shot 11.6- feet). They surveyed some tight, nasty crawls that eventually tied into the EI survey, closing a 500-foot loop.
During March and April of 1998, 703 feet or 0.13 miles of cave was surveyed and inventoried on 3 trips in Wind Cave, raising the cave from 81.56 miles to 81.69 miles. A total of 94 stations of previously surveyed cave was also inventoried.
Tim Moreland, Dennis Laird & Andy Christiansen
Tim led a survey trip to the Red Crystal Canyon area of the Colorado Grotto Section, where they surveyed 286.3 feet in 15 stations during a 13 hour trip (Avg. shot 19 feet). They also inventoried 19 stations of the IH survey.
Jamie Sherer & Steve Turner
Jamie led a 11½ hour trip to the Historic Section, where they surveyed 102.1 feet in six stations (Avg. shot 17 feet). They were also able to find a survey blunder in a bad loop. In addition, they inventoried 24 stations along the UK survey.
James Wilson, Dan Sadler, Kenny Bagby & Paul O’Brien
James led a 12½ hour trip to the Club Room, where they surveyed 315 feet in 24 stations off the AS survey (Avg. shot 13.1 feet). They located several leads for a later trip.
Myk Coughlin, Steve & Sammy Langendorf
Myk led a 5½ hour trip to the Club Room area, where they inventoried 51 stations along the IT survey. They noticed several highly-coated helictite bushes in the area
