The federal protection order for the Ash Ridge Geothermal Preservation Zone came through forty-three days after Marcus filed the emergency paleontological claim with the Bureau of Land Management's restricted fauna division. Forty-three days was, by government standards, extremely fast.
Marcus credited this to the comprehensive nature of the field data package—twelve hours of acoustic mapping, seventeen species of documented preserved flora, six documented preserved fauna species (including three previously unknown to science), and biological sample analysis confirming active DNA signatures consistent with Cretaceous-era genetic markers—combined with the fact that the filing included four hundred and thirty-seven high-resolution photographs of a living, free-moving Deinonychus antirrhopus interacting voluntarily with human researchers.
The photographic evidence had been Reyes's contribution. She had been photographing Talon from the first hour, quietly and systematically, in between sketching his feather structure in her field journal. The resulting portfolio was, as the lead scientist at the National Natural Science Foundation described it in her response letter, "the single most significant biological documentation in the history of vertebrate paleontology."
Vanguard Resource Corporation's geological extraction permits were suspended pending environmental review. The review was expected to last approximately four years, during which the federal protection order rendered all surface drilling activity in the Ash Ridge Formation a Class A federal violation.
Commander Harrow had, to Marcus's professional acknowledgment, cooperated fully with the federal investigation following her evacuation. She had surrendered the seismic array data and her company's survey documentation, and had testified that the magma surge had been an unintended consequence of the seismic charge sequence.
The legal situation for Vanguard was complex and ongoing. The Ash Ridge Primeval Reserve was established formally on a cold October morning with a small ceremony attended by three federal officials, the University of Colorado's Department Chair, Reyes, Patel, Marcus, and two documentary film crews whose presence Marcus had reluctantly agreed to as part of the public education funding arrangement.
The preserve boundaries encompassed four hundred acres of Ash Ridge Badlands surface terrain, the full extent of the confirmed geothermal cavity system, and a buffer zone of two kilometers in every direction. At the center of the ceremony site—directly above the repaired and newly reinforced surface access shaft—Marcus stood beside the monument marker as the federal official read the legal establishment language.
He was watching the shaft entrance. After forty-three days, Talon's thermal signature had returned to the upper cavern network three times—detectable on the monitoring equipment installed at the shaft entrance. The raptor had investigated the shaft opening each time, spent between twenty minutes and two hours in the upper gallery, and descended again.
The ecosystem's apex predator was aware of the surface. Was choosing to acknowledge it. And was choosing, each time, to return to the world it had always known.
As the ceremony concluded, Marcus moved to the shaft entrance and looked down. The warm air rose from the depths, carrying the now-familiar mineral scent of the geothermal oasis. From somewhere in the warm darkness below, a sixty-four-hertz pulse drifted upward—steady, rhythmic, directed.
Talon, checking that Marcus was still there. Marcus pressed his palm to the warm shaft rim and let the pulse vibrate through his bones for a moment.
"Still here," he said quietly into the dark.
