How far are the glaciers from Bartlett Cove and which glaciers are the best to see?
There are 10 tidewater glaciers in Glacier Bay National Park and Preserve. McBride Glacier, the only tidewater glacier in the East Arm, is approximately 40 nautical miles from Bartlett Cove. In the West Arm, Margerie Glacier is approximately 55 nautical miles from Bartlett Cove while Johns Hopkins Glacier is about 63 nautical miles away. If you are on short visit your best bet is to head to the West Arm for glacier viewing. John Hopkins Glacier is perhaps the most scenic of the park's tidewater glaciers. If you are kayaking, McBride Glacier is a good destination because it attracts fewer motorized vessels and is a very active glacier. However never paddle (or take a boat) into McBride Inlet due to its hazardous entrance.
How old are the glaciers in the park?
Glacier Bay has experienced at least 4 glacial periods. The last, the Little Ice age, began about 4,000 years ago. The glaciers that still exist in the park today are remnants of that glacial period.
How old is the ice at the face of the glaciers?
Glaciers flow forward about 3 - 6 feet each day. Depending on the length of the glacier and the steepness of the valley it flows through, the ice at the front of the glacier is anywhere between 200 and 75 years old. So snow that fell in the high mountains 200 years ago, when the U. S. Declaration of Independence was signed, calves (breaks off) off as ice today.
