Mount Thielsen

With its spire-like summit, Mt Thielsen is easily recognizable. Below its steep top, Thielsen has many fun slopes to ski as long as the weather and snow pack are right. Weather is always something to watch out for in the mountains and this mountain is no different. The pointy top of Mt. Thielsen seems to act as a lightning rod drawing an amazing number of lightning strikes each year. Also, with some slopes approaching 40 degrees, avalanches are not uncommon on the mountain. But if conditions are right, lines of up to 3,600 vertical ft are possible!

Part of the High Cascades, Mount Thielsen, at 9,184 ft, is a prominent feature of the area. It is considered an extinct shield volcano. A shield volcano is generally large and low in profile, forming from fluid lava flows. However, because it's lava flows stopped around 250,000 years ago, glaciers have eroded the peak to its current form.

Food & Water

For water, 2L-3L per person for a day trip is recommended. As for food, several small snacks throughout the day are recommended. Big meals are fun but bog you down. Small snacks allow for a continual flow of energy to your body. For your snacks, try to balance sugars, fats, proteins, and carbs so your body is continually fueled. This helps reduce crashes in energy during the day.
