The record, newest first
The council approved the annexation and business-park rezoning on third and final reading, 8-2. (Cowboy State Daily, Sept. 29, 2026)
On second reading the annexation and the two zoning ordinances passed 6-3. (Wyoming Tribune Eagle (Laramie Boomerang), Sept. 17, 2026)
At a council work session, the developers described two to three buildings on the southwest part of the property, closed-loop cooling, a written 'Commitment to the Cheyenne Community' and an agreement to transfer the mausoleum land to a Cox family foundation; they said financial commitments were hard to make before a project was certain. (Wyoming Tribune Eagle, Aug. 28, 2026; Y95 Country, Aug. 25, 2026)
Cheyenne LEADS listed the ViaWest/Skybox Happy Jack site among planned data centers in Laramie County. (Cheyenne LEADS, Aug. 4, 2026)
Residents of the nearby Rolling Hills area opposed the annexation over traffic and water use, and an attorney for the former owners raised the fate of a family mausoleum on the ranch. (Cowboy State Daily, April 27, 2026)
At the request of the developer's attorney, the council voted 9-1 to send the annexation back to committee and take it up again in September. (Wyoming Tribune Eagle via Wyoming News Exchange (News Letter Journal), April 29, 2026)
The council's Public Services Committee voted 2-1 against recommending the annexation of about 1,260 acres for a data center. (Wyoming Tribune Eagle via Wyoming News Exchange (News Letter Journal), April 29, 2026)
Conflicts and open questions
- Acreage varies: the annexation covers about 1,198 acres (Tribune Eagle; Y95 Country gives 1,197.76), while the ranch is described as about 1,260 acres (Tribune Eagle in April; Cowboy State Daily).
- The April 27 vote to send the annexation back to committee was 9-1 per the Tribune Eagle; Cowboy State Daily (Sept. 2026) described it as unanimous.
- The second-reading date (Sept. 14) follows from the Tribune Eagle's report of a Monday vote published Sept. 17 and the scheduled council date.
- Coordinates are approximate, placed from the reported location (west of Roundtop Road, along Happy Jack Road); the parcel was not mapped.
- Cheyenne LEADS lists the site as planned ('ViaWest/SkyBox - Happy Jack').
