William Bruce Harrison, an oil heir who has largely remained a recluse, is at the center of a growing controversy in Colorado's San Luis Valley due to extensive fencing and development plans on his 83,000-acre Cielo Vista Ranch. The 39-year-old purchased the ranch, which includes the 14,047-foot Culebra Peak, for a reported $105 million in 2017. He has erected 26 miles of 8-foot-tall barbed wire fencing and plans to build a large compound featuring a private helicopter hangar, snowmobiles, and ATVs, which locals have dubbed a "toy box."
Critics, including third-generation land grant heirs and environmental groups, argue that the fencing disrupts centuries-old water irrigation channels, blocks wildlife migration corridors, and poses a threat to endangered species. Shirley Romero Otero, 70, a co-founder of the La Sierra Environmental Guardians Committee and an heir to the Sangre de Cristo Land Grant, stated that Harrison's actions send a message that he can disregard the damage he is causing to the community and the environment. Otero, who has fought for her community's land rights for five decades, views the situation as a class war waged by an outsider against an indigenous community.
A jointly commissioned wildlife report released this month confirmed many of the locals' fears. The report found that the fence impedes the movement of elk and mule deer, potentially leading to weakened animals unable to find alternative routes and increased instances of miscarriages in pregnant animals. The document also warned of the fence trapping wildlife during wildfires. Even Harrison's designated "wildlife jumps" were deemed inadequate, failing to keep calves and fawns with their mothers. The report recommended significant modifications, including lowering fence sections, raising the bottom wire, and in some ecologically sensitive areas, removing the fence entirely.
Locals also expressed concern over hunting rights. Florentino Rael, 31, who grew up near the ranch, recalled shooting his first elk from his living room window, an experience he believes is now impossible due to the restricted animal movement. He fears the fencing is destroying a generational culture tied to the land.
Harrison, described as a "digital ghost" due to his lack of public presence and interviews, inherited his fortune from the multigenerational Dan Harrison oil empire. He secured full control of his inheritance after a legal battle with his uncle in 2017. While his attorneys have previously stated that critics seek to "dehumanize and demonize" Harrison, locals like Bernadette Lucero question his motivations, noting he visits the ranch infrequently despite significant investment in the fence and a planned mega-mansion.
Despite the ongoing dispute, some legal and legislative actions have been taken. In September 2023, county commissioners voted to ban new high fences, followed by a preliminary injunction. State water quality officials cited Harrison's team for water flow disruptions. In 2025, Colorado Governor Jared Polis signed legislation imposing new restrictions on fences taller than 5 feet in the Sangre de Cristo land grant area, a law widely seen as targeting Harrison's development. However, these measures have not resulted in the removal of the existing fence.
Adding to the tension, Harrison recently filed plans for a 7,000-square-foot home and a 233-acre security buffer zone around his proposed compound. Land-rights attorney Madeline Finlayson criticized this buffer as exceeding the privacy afforded to global leaders.
Some locals who were previously granted access to the ranch report that Harrison's security measures, including guards, cameras, and drones, create a prison-like atmosphere. Despite the community's sustained efforts and some legal victories, the future of access and environmental protection on Cielo Vista Ranch remains uncertain, with some, like Rael, expressing pessimism that the fence will ultimately prevail.
