The radio crackled back within ninety seconds. "Copy, Iron Peak Station. This is Coordinator Petra Halvorsen. We're receiving your alert. Can you give me a confidence level and estimated timeline? Over."
Julian looked at Kira. The lynx had risen to her feet and was pacing the granite shelf, her ember-tipped ears cycling at high frequency. Every trained instinct Julian had developed over three winters at this station told him the timeline was short.
"Confidence level: high. Estimated onset: eighteen to thirty-six hours, possibly less if the storm front arrives ahead of the current projection track. I recommend activating evacuation protocols for Sector Seven immediately. Over."
A pause on the radio. Then: "Understood, Observer Vance. We're initiating precautionary evacuation. County emergency services are being notified. Will you be deploying controlled release charges? Over."
Julian was already doing the math. Iron Peak Summit Station maintained a magazine of four Type-9 directional blast charges specifically for controlled avalanche release operations. The charges were designed to fracture the snowpack at a chosen point, triggering a controlled slide along a safe vector rather than an uncontrolled catastrophic release along the village approach corridor.
"Affirmative, Coordinator Halvorsen. I will conduct a site assessment on the north face for optimal charge placement. Conditions are currently workable. Over."
The next storm front was showing on the long-range radar as a dense orange-and-red band crossing the western range. Julian estimated he had a six-hour window of manageable conditions before the second front closed the summit. After that, neither human movement on the north face nor any kind of precision charge work would be possible.
He retrieved the blast charge transit case from the equipment locker inside the station and lashed it to his external pack frame with three-point tie-down straps. Four charges, four detonator caps, digital timer units, and the deployment tool kit — total weight, eleven kilograms.
Julian ran the approach vector calculations twice on his field tablet, checking every variable against the current wind conditions, charge placement geometry, and the topographic debris flow models stored in the station's planning database. The mathematics confirmed what his field experience already told him: a four-point sequential charge pattern along the identified fracture line would generate a controlled release channeled entirely into the Felden Gorge, leaving the village approach corridor completely unaffected.
He packed the blast charge transit case with careful, deliberate movements, checking each component against the equipment manifest before sealing the case.
The blast charge transit case had been inspected and restocked eight months earlier during the annual equipment audit. Julian had logged the restock personally, verifying the condition of each charge, timer unit, and detonator cap against the manufacturer's specifications.
The Type-9 directional charges had a rated shelf life of five years from manufacture date — all four units in the magazine were well within that window. Julian ran the pre-deployment self-test sequence on each timer unit before sealing the case, confirming that the electronic triggering circuits were functioning correctly.
He noted the test results in the operations log with timestamps, following the procedural documentation requirements that the Mountain Safety Authority mandated for all blast operations.
Julian conducted his final personal equipment check at the station entrance before stepping out onto the north-face approach trail. Avalanche transceiver switched on and transmitting, confirmed against the station's receiver unit.
Ice axe secure on left hip harness. Crampons fitted and binding levers locked.
Probe poles collapsed and stowed in the external pack side pockets. Emergency bivouac kit sealed and stowed.
Radio harness fully charged and set to the emergency coordination channel. Field camera secured in the chest harness pocket.
The blast charge transit case latched and secured on the external frame. He ran through the check list one item at a time, touching each piece of equipment as he named it — the same routine he had followed at the start of every single field operation in three winters at Iron Peak.
The routine was not superstition. It was the accumulated discipline of working alone in an environment where a single missed item could become a fatal error.
The transit case had a bright red corded carrying handle and a yellow warning stripe across the lid panel — colors chosen for high-contrast visibility in low-light and storm conditions. Julian had thought about those design choices during his equipment training and had concluded that whoever had specified them had understood the operational context precisely.
In alpine terrain in deteriorating weather, with cold-numbed fingers and wind-obscured visibility, every ergonomic and visual aid that equipment designers could build into hazardous material handling systems reduced the probability of handling errors. Julian appreciated that kind of thoughtful engineering.
