Key Wyoming state leaders said late Thursday that for $100 million they are willing to sell a state-owned parcel inside Grand Teton National Park to the National Park Service.

But the deal comes with a condition: The Bureau of Land Management must not include strict oil and gas and underground pipeline restrictions in a management plan for federal lands in southwest Wyoming.

Otherwise, no sale.

The five-member Wyoming State Board of Land Commissioners voted 3-2 to approve the sale of the “Kelly Parcel” nestled within the picturesque Gros Ventre River Valley on Grand Teton’s eastern border.
