The Ashlu River flows into the Squamish River about 40 km away from its end at Howe Sound. The river made Ashlu Canyon, a very deep very narrow east-west chasm. The south face keeps the river shaded all the time so this river is the last in the Vancouver area to lose its ice. This photograph shows the detail from a very small part of the river.
This photograph was made with a relatively slow shutter speed of 0.25s with the camera on a tripod - a cable release and mirror lock-up helped keep the vibrations down. Kodak Gold 100 film was used, it was scanned at 10,000 samples per square millimetre. This picture shown is cropped a little from the original composition.
