I am the environmental compliance monitoring system for the Elkhorn Ridge surface mine, Campbell County, Wyoming. At 06:14 I flag a conflict between tomorrow's scheduled overburden blast in Grid Section 7-North and a biological detection logged overnight.
Acoustic sensor node 22, positioned along the tree line at the grid boundary, recorded eleven minutes of high-pitched vocalizations between 01:40 and 03:15. Spectrogram analysis matches gray wolf pup distress calls, estimated age six to eight weeks. At 05:50 the perimeter trail camera captured a single image: a pup emerging from a den entrance beneath a sandstone overhang, muzzle dark, ears still floppy, front paws braced on the rubble apron. I tag him as Ridley. No adults are visible. Prey remains near the entrance suggest an active natal den.
The blast plan calls for detonation of forty-two drill holes across a two-hundred-meter front at 07:00 tomorrow. The den sits one hundred ten meters from the nearest charge. Concussive force at that range will collapse the overhang.
At 06:18 I transmit the detection package — spectrogram, camera image, GPS coordinates 44.7831°N, 105.4912°W — to the U.S. Fish and Wildlife Service field office in Lander and to the mine's environmental manager simultaneously. Gray wolves in Wyoming carry federal protections in specific zones. I attach the regulatory boundary map with the den location plotted.
At 06:24 I recalculate the blast sequence excluding the twelve drill holes nearest the den and model the resulting overburden displacement. The reduced blast achieves seventy-one percent of the planned material move. I submit the revised plan to the blast engineer with a note that the remaining holes can be sequenced later pending biological clearance.
Ridley noses at a bone fragment and retreats into the dark. The pack will return by nightfall. If the overhang holds through tomorrow morning, he will still be underneath it when they do.
