Geocache Description:

The listed coordinates will take you to a great view point in the Stawamus Chief Provincial Park.

From this view point you will be able to look back to the Howe Sound Fjord.

What is a Fjord?

A fjord is a long, deep, narrow body of water that reaches far inland. Fjords are often set in a U-shaped valley with steep walls of rock on either side.

Fjords are found mainly in Norway, Chile, New Zealand, Canada, Greenland, and the U.S. state of Alaska.

Fjords were created by glaciers. In the Earth's last ice age, glaciers covered just about everything. Glaciers move very slowly over time, and can greatly alter the landscape once they have moved through an area. This process is called glaciation.

Glaciation carves deep valleys. Glaciated valleys are formed when a glacier travels across and down a slope, carving the valley by the action of scouring. When the ice recedes or thaws, the valley remains, often littered with small boulders that were transported within the ice Fjords are found in locations where current or past glaciation extended below current sea level. A fjord is formed when a glacier retreats, after carving its typical U-shaped valley, and the sea fills the resulting valley floor. This forms a narrow, steep sided inlet connected to the sea.

Howe Sound Fjord

The Coast Range, along with most of North America, was affected by a series of glaciations from about 1.6 million years ago to as recently as 11,000 years ago. Modern glaciers are relics of this ice sheet and still cover high parts of the Coast Ranges. During the last ice advance (Fraser Glaciation) 25,000 to 11,000 years ago, glacier ice up to 2,000 metres thick filled what is now Howe Sound and flowed over all the present peaks of the Britannia Beach area. The rounded character of the peaks on the islands of Howe Sound and the west slopes of Howe Sound attest to the sculpting by the southward flow of ice.


To log this earthcache, you must email (or message) me the following information:

1) What is the elevation in metres (per your GPSr) at ground zero?

2) Looking across the Howe Sound Fjord estimate the width of the Fjord. (Give your best guess in metres)

3) Look west across the Howe Sound Fjord, what evidence do you see of the last glaciation?

4) Optional request: If you wish, please post a picture of yourself or your GPSr with the Fjord in the background.
