About coldSTONE Mountain Works
coldSTONE Mountain Works was founded by Bryce Tangvald and Mike Kann — a partnership built on the belief that the most valuable experience is earned on the move through serious terrain.
Between us, we bring decades of experience across the UK’s crags, mountains and coastal cliffs, and into more complex alpine ground, including over twenty years spent climbing and travelling in the Dolomites.
Two perspectives. One approach.
Our backgrounds differ, but our approach is shared.
We design journeys rather than isolated experiences. Some are guided expeditions, some focus on capability-building, and others are structured independent traverses. In each case, terrain and conditions shape the day.
Skills are introduced when they matter. Decisions are made in context. Progress is measured not in certificates, but in confidence, judgement and depth of experience.
Mike Kann
Mountaineering and Climbing Instructor
Mountaineering & Climbing Instructor
Mike is a Mountaineering & Climbing Instructor with a background in technical instruction and equipment design. His work focuses on steeper ground — scrambling, climbing and the decisions required when terrain becomes more complex.
His approach emphasises fluid application of skills in real situations, where judgement, timing and movement matter as much as technical ability.
Bryce Tangvald
Mountain Leader and Rock Climbing Instructor
Bryce is a Mountain Leader and Rock Climbing Instructor with a background in wilderness medicine and a wide range of outdoor professional roles. His focus is on the quieter skills of mountain travel — movement, navigation, pacing, and awareness — and how they combine over long days and multi-day journeys.
His leadership is defined by attention to rhythm and flow, ensuring that time in the hills builds confidence and capability beyond the immediate objective.
