Hubbard Glacier is a glacier located in Wrangell–St. Elias National Park and Preserve in eastern Alaska and Kluane National Park and Reserve in Yukon, Canada, and named after Gardiner Hubbard. Wikipedia

The Sawyer glacier is actually divided into two separate glaciers: North and South. The South Sawyer Glacier at the end of the Endicott Arm fjord can be very difficult to access, and is only visible on limited days of the year where there is good weather. The North Sawyer Glacier is the more common part that people visit, and it’s the one located at the end of Tracy Arm fjord. The glacier itself is white above ground, giving way to an incredible cobalt blue as it extends deep under the surface of the ocean.

The face of the glacier is about a half mile wide, make it easy to view from the water (you cannot access it from the land). It’s an active tidewater glacier, which means that you can often see “calving” events where a large chunk of ice breaks off and falls into the ocean below. The ice that falls off could be a small chunk or a section the size of a cruise ship, depending on the day. The ice chunks hit the water below, which reaches depths of as much as 600 feet, and also has sections of the glacier under the surface. In fact, calving events can also happen underwater, and you will see the calved chunk of ice emerge from the water like a submarine and float away.

On either side of the Tracy Arm are mountain peaks that soar to 7,000 feet above sea level, and you can find waterfalls and wildlife all over the faces of the cliffs. If you look closely you can often catch a glimpse of mountain goats, seals, and birds on the glacier itself or the nearby mountain slopes, and might even be lucky enough to see a whale or two in the water below.
