We are an international climbing and skiing guide service owned and operated by UIAGM / IFMGA Certified Mountain Guides Kathy Cosley & Mark Houston. We specialize in small-group and custom climbing and skiing trips and expeditions to the great alpine destinations of the world. Our programs include mountaineering, rock and ice climbing, expeditions and ski mountaineering.

This is a great high altitude expedition for experienced climbers. Chopicalqui is a beautiful summit in the very center of Peru's Cordillera Blanca. To acclimate, and also for the fun of it, we'll climb several other summits in the Ishinca area, including 6032 meter Tocllaraju.

In a new kind direction, Kathy will offer a cultural tour in the Hautes Alpes region near Briançon in June. This tour focuses on pastoralism and combines light hiking in the Queyras mountains, with workshops in such fiber arts as felting, vegetable dyeing, and hand spinning, led by some new friends she has made near Serre Chevalier..

This is a challenging high altitude trek linking the Chamonix Valley and Zermatt. For much of this route we are on glaciers or off trail, on climbers paths and routes. We'll stay in mountain huts, rise early and enjoy long days in high alpine terrain. This 7-day route is distinctly more difficult than the Walker's route (below), but offers the rewards of a greater challenge.

The classic Swiss countryside trek. This is a 6-day trek with an optional 3-day add-on ascent of the Wildstrubel. The trekking portion links remote villages in what is arguably the most quintessentially "Swiss" alpine scenery in the country. We stay in small hotels and inns, and the trekking is on trails (though occasionally quite rough). The optional Wildstrubel ascent is a great introduction to glacier climbing and offers a fine finish.

We spend every summer guiding in our backyard, the Alps. Let us know if you think you might like to join us.

This version of the Chamonix to Zermatt Haute Route avoids the more rigorous glaciers and off-trail hiking of the "Glacier Trek" (above). But even though the route stays on trails, and lodging is in more comfortable village inns, it is still a demanding hike, with some big days. The entire program is 9 days of alpine trekking.

In January of 2013, we are heading back to Argentina to climb the highest peak in the western and southern hemispheres. Our route of choice includes a traverse of the peak, ascending the Vacas and Relinchos valleys to the Plaza Argentina Base Camp, and descending via the normal route on the Horcones side.
