The descent route to the glacier's upper crown required crossing three hundred meters of steep, wind-hardened snow on a thirty-two-degree slope. Julian moved methodically, kicking each crampon firmly into the surface before transferring weight, while Kira ranged ahead and to the sides, pausing regularly to orient her thermal senses toward the snowpack.
The process was not random. Julian had learned over eighteen months to follow Kira's navigation precisely, matching his route to the areas where her fur showed the lowest thermal activity — the safest, most stable snow corridors. Where her fur brightened significantly, Julian stopped, assessed visually, and chose an alternative line.
Forty minutes into the descent, they reached the upper glacier staging area — a broad, relatively flat section of old compressed glacier ice that served as Julian's preferred working platform for north-face operations. From here, the glacier's fracture zone was visible as a subtle convex bulge in the snow surface approximately eighty meters below.
Julian set up his directional assessment scope and began marking charge placement coordinates. The goal was to create four precisely spaced fracture initiation points along the glacier's compression zone, triggering a controlled sequential release that would channel the sliding snow into the Felden Gorge — a deep, uninhabited gully that ran parallel to the village approach corridor.
Kira paced the staging area carefully, then stopped at a specific point twenty meters to Julian's left and sat down facing the glacier face. She pressed both front paws onto the ice surface and held perfectly still, her amber fur glowing at maximum intensity.
"That's it," Julian said quietly, moving to where Kira was sitting and scanning the surface around her paws with the ground-penetrating radar unit. The radar return showed a clear fracture initiation plane approximately four meters below the surface, running diagonally across the glacier at precisely the angle needed for the controlled release vector. Kira had found the exact line.
The portable ground-penetrating radar unit returned clear, sharp readings across the entire staging area. Julian worked systematically from north to south, building a precise subsurface thermal and structural map of the glacier crown in the critical zone.
Kira moved alongside him, her thermal sensing providing an independent biological verification layer that complemented the instrument data in ways that never ceased to impress him. Between the radar readings and Kira's behavioral responses, he had the most accurate pre-event glacier assessment he had ever produced in three winters of north-face operations.
Working the ground-penetrating radar across a steep, wind-exposed glacier crown in thirty-knot winds and negative-twenty temperatures required a level of physical and mental focus that Julian found both demanding and clarifying. Every scan had to be conducted at a specific angle relative to the slope to obtain accurate depth readings, which meant constant careful positioning on the cramponed surface.
Kira moved around him like a counterweight, her presence grounding and orienting in ways that went beyond the thermal sensing data she provided. Julian had come to understand over eighteen months that working alongside Kira was a fundamentally different experience from working alone — not just because of the safety margin her sensing ability added, but because the lynx's calm, focused attention to the environment helped calibrate his own.
The portable radar unit's display built up a subsurface structural map of the glacier crown over the course of the assessment sweep, rendering the data in colour-coded depth layers on the small screen. Julian photographed every frame at each scan station, building a complete photographic record of the subsurface conditions alongside the electronic data log automatically saved to the unit's onboard memory.
The imaging confirmed what the surface topography and instrument data had already suggested: the fracture initiation plane that Kira had located with her paws was continuous across the full width of the glacier crown — a clean, well-defined layer of weakness running at a favourable angle for the controlled release vector. The planned charge placements would intersect this plane at optimal spacing intervals to produce the sequential propagation effect that directional blast engineering required.
Julian annotated each scan position on his topographic overlay with the precise charge coordinates and submitted the annotated map to the Mountain Safety Authority via satellite uplink while still on the glacier staging area.
He completed the north-south radar traverse in forty-eight individual scan stations, each precisely spaced at six-meter intervals across the glacier crown. The complete subsurface map, assembled from all forty-eight stations, showed a fracture plane that was consistent in depth and orientation across ninety-one percent of the measurement area.
The nine percent at the eastern margin showed a slightly different depth profile, which Julian accounted for in his charge spacing calculations by placing the fourth charge at a slightly different depth setting from the other three. The adjustment was small but necessary for the sequential propagation pattern to function as designed.
