Take an Alaska glacier tour and find our first hand what causes pressure ridges to form on a glacier. During a recent Alaska glacier tour an experienced guide led several groups on a tour of pressure ridges that formed on top of the frozen Matanuska River. What is a glacier pressure ridge? A pressure ridge […]
One question we get asked here consistently is if we have wildlife on the glacier. Since the only plant life on the glacier is the glacier moss, there isn’t any sort of food source that would sustain animals such as moose and bear. Therefore, you wouldn’t see anything of the sort on the ice unless […]
Anchorage is the largest city in Alaska. It boosts five-star dining and hospitality while at the same time it is surrounded by wildlife, breathtaking views, and adventure. Here are are a few of our favorite things to do near Anchorage, Alaska. If you like an adventure than this list is for you. Alaska Wildlife Conservation […]
Due to harsh conditions, cold climate, and lack of soil on the glacier’s surface, it is quite impossible for anything – even bacteria – to effectively survive and thrive. The Matanuska glacier sits between the Chugach and the Talkeetna mountain ranges, and because glaciers are ever-moving forms, it is constantly grinding away at the bedrock it sits upon as well as the base of either range. When this occurs, sediment and plant debris get drawn into many circulating subterranean channels that travel chaotically below and above the glacier’s surface. Much of this sediment and debris get circulated and deposited throughout the glacier, often on its surface. A large portion of this plant material consists of Bryophyta, which classifies most mosses. Mosses stem from primordial plants that are extremely resilient and hearty, exemplified through their ability to thrive after prolonged periods of cryptobiosis. Cryptobiosis is the process of metabolic activity in an organism slowing to the point of almost being undetectable, which particularly occurs in freezing. Moss, particularly acrocarpous moss, is highly adaptable and can reproduce asexually, so when fragments that have been frozen for extended periods of time are exposed to sunlight they can spontaneously begin to photosynthesize again.
When this occurs, these fragments adhere to small particulates of sediment and grow around its surface entirely. Because glaciers are always moving, these new forms begin to rotate and flip, exposing all sides to sunlight and promoting growth to continue in a layered process like that of an onion. These globular forms can grow to the size of basketballs, and maintain an internal temperature of 5 degrees above the surface of the ice they sit upon, even in the winter. Because of this incubatory factor, tiny microorganisms and invertebrates can survive within – typically about 70 per quarter-sized moss ball.
In the early 1950s, these globular forms of moss were given their playful name by Swedish plant biologists studying Falljokul glacier in Iceland, who came across a large dispersal of these cute rounded clumps, and coined them “Glacier Mice”. Here on Matanuska Glacier, you can see these throughout your trek on guided and unguided trails, particularly in the summertime when they are soaking up the sun and glowing that fabulous fluorescent green against the ice!
Summertime tours are now available which means trekking across glacier terrain, drinking glacier water, and sunshine. We are open seven days a week! Due to summer conditions, ice caves are no longer available for exploring. However, ice cave tour season will be back before you know it! Give us a call for more information […]
Happy Spring! Here in the Matanuska Valley, we are experiencing rising temperatures and bluebird days. That means we are transitioning from the winter season to the summer season. Here are some of our recent pictures for you to enjoy. We hope you come and enjoy the glacier before the winter conditions are gone! We are […]
Here at the Matanuska Glacier, we have plenty of blue ice to explore! Vibrant colors shine in both the winter and summer seasons for our clients to enjoy and photograph. Ever wonder why blue ice is blue? Well, due to the chemical bond between oxygen and hydrogen in water, it absorbs light in the red […]
Looking for an authentic Alaskan adventure? We got you covered. The Matanuska is the largest glacier accessible by car. Beginning in the northern snow and ice fields of Mount Witherspoon (12,023 feet) and Mount Marcus Baker (13,176 feet), it begins its descent from a hanging glacier to the valley floor. The Chugach mountains receive the […]
November 14, 2017 Yet another Alaskan winter is upon us here at the Matanuska Glacier. The snow has fallen, covering the many cracks and crevasses of the glacier. With this, glacier caves are beginning to form within the ice. Caves are carved out by water running through the glacier producing one of the most popular […]
