Malcom Knapp Research Forest

Located in the foothills of the Coast Mountains, ~60 km east of Vancouver, the forest contains just about every type of terrain found in southern coastal BC. The forest stretches north and east up the slopes of the Golden Ears Mountains to ~1000 m above sea level, west down to sea level at Pitt Lake, and south to the edge of the urban interface in Maple Ridge.
As typical of coastal BC, the forest receives a lot of precipitation, mostly as rain--from ~2200 mm/yr y at the southern end to ~3000 mm/yr at the north. Snow is rare at the south end of the forest, while the higher elevations to the north are typically snow covered for four months of the year. The forests are dominanted by coniferous trees, the most common of which are Douglas-fir, western redcedar and western hemlock.

Please note - the MKRF is not open to the public, so this field trip cannot be conducted by those outside of guided groups.

Site 1: Bridge over the Allouette on 'A' road

Excellent example of bed rock controlled channel. Trail down to river edge on the left hand side of the road. Parking space for ~2 vehicles Not suitable for gauging. Would be very dangerous in high flows.

Site 2: East Creek Sign

Little blurb about the history of East Creek and the research that is being conducted there. Good example of the effects of logging on a creek as there is a clear cut right to the edge of the creek on one side of the road and the other side has mature second growth. Lots of sunlight on logged part and algae growth.

Site three: Crossing of Alouette on K road

Open, wide (~10m) channel. Partially bedrock controlled. Good cross section for gauging. In the flow conditions we saw, it could have been crossed in just rubber boots. Easy access to the river. Large parking area for many cars. Shortly down stream of Marion Lake so very few fines present. Channel appears starved of sediment.

Site Four: Confluence of Mayfly and Alouette. Site of Jon Richards experimental channels.

Good site for bulk samples on the Alouette. Could also be used for gauging. Would be possible in rubber boots. The Mayfly is considerable steeper and is depositing much coarser material in a small fan as it reaches the Alouette. Very rapid change in grain size. Trail from study site to creek a bit bushy.

Site Five: Access to Mayfly off of 'B' Road

Creek is clogged with log jam (all cut timbers - man made?). Large accumulation of fines up stream. Not very interesting. Old abandonded artifical channel site of same design as the one lower down.

Site Six: Crossing of unknown creek on 'E' road.

Very high sediment supply with large midchannel bars. The creek is about 5m wide and crossable in gum boots. Not suitable for gauging.

Site seven: Unknown creek off of E10

E10 is very rough, requires HC 4x4 Can hike up from main road ~5-10 mins Still large supply of sediment, partially bedrock controlled There is a study here by Kim ? on trout.

Site Eight: Cut into glacial-marine sediment

Mostly covered in sluff. There are two exposures, one in a pit just off the highway and another up a small road ~15m long. 0.5 to 1 meter of exposure and could probably see more if you had a shovel.

Site Nine

Just down the road you cross a bridge over a small (~5-8m wide) creek with step pool morphology. Good access on the right bank down old road. There is an old shed with large water intake.

Site Ten: Unknown creek crossing 'G' road
