Yellowstone National Park is soliciting proposals from businesses interested in providing guided, interpretive over-snow vehicle tours of Yellowstone National Park. There are 23 new contracts available for the 2014-2015 winter season. Park Spokesman Al Nash says they will take the place of 13 concession contracts for guided interpretive snowcoach tours and 21 commercial use authorizations for guided interpretive snowmobile tours currently in place in Yellowstone. Nash says, “These are not simply someone raising their hand and telling us that they’re interested in offering service. This is going to be a competitive process.” He says there are opportunities available at each of the entrances to the park, and there is a prospectus available online that interested parties can download, and then they have a couple months to submit their prospectus. The current concession contracts expire at the end of this season. New proposals will be due January 27th.
