The area was first mapped in 1995 at 1:15000 by Martin Pardoe and his map has been used for major events in the past. Sage O Club uses the map for introductory O events each spring.
The map area is within the City of Kamloops and the land is part of the City’s Parks system. The western side of the map is part of the Kamloops Bike Ranch which is operated by the Performance Cycling Centre in cooperation with the City of Kamloops. The “Ranch” is known throughout Western Canada as the “place to go” for bike riders who enjoy jumps. The east boundary of the map is private land and is marked by an un-crossable fence. On the western edge there is a major city road. North and South boundaries are steep grassy slopes.
About ten thousand years ago the map area lay beneath a large lake that was created by ice lobes blocking the North and South Thompson valleys in the vicinity of Kamloops. The ice dams collapsed and the water drained westward in a catastrophic event. Rapidly flowing water carved deep gullies in the former lake bed leaving the land much as you see it today. The gullies and cliffs have remained quite stable in the dry Kamloops climate. Building has not been permitted because of the risk of foundations being weakened as a result of water action.
The map is almost entirely open grassland, mapped as rough open. There are patches mapped as open land which is generally packed dirt and occurs in areas where bike trails and jumps have been built. Prominent trees and bushes have been mapped but small patches of trees have been mapped as rough open land with scattered trees. There are a few small areas of white forest. Some portions of the grassland are mapped as slow running because of knee-high to chest-high sagebrush.
Kamloops was heavily hit by the mountain pine beetle epidemic in the years between 2005 and 2007 when many large ponderosa pine trees were killed. There are many fallen trees on the map and individual stems have been mapped as solid green lines showing the approximate length and alignment of the fallen tree (they are visible on the aerial imagery). Patches of deadfall are marked as slow running.
Many un-crossable cliffs are mapped along the edges of the gullies. The cliffs are silt, not rock, and look like very steep earth banks. There are also many earth banks mapped as crossable.
Man-made features are common throughout the map. The main trail network has been created by bike riders and walkers, but bike riders have created many new trails in the western half of the map. There are a few vehicle trails. Within the western part of the map there are many bike jumps carved into the silt. Some are very large (>5m). They are shown by contour lines and form lines, and by knoll, bank, and wall symbols. There are numerous prominent manmade features including wooden ramps for jumps, signs and small buildings. There is one large building and parking lot – the Valleyview Ice Arena – which will be used as the Event Centre.

Hot weather is a normal summer hazard in the BC interior and this summer is no exception. No Water will be provided on the sprint courses. Competitors should take their own precautions. Make sure you are well hydrated before your start time and take water with you if you expect to be out on the course for a lengthy period of time.
The map covers part of the Kamloops bike Ranch. The Bike Ranch will be closed for the morning of the Sprint event with the cooperation of the City and the Bike Ranch operators but it is possible that bikers will try to use the area. Stay alert!
Please do not climb the bike jumps. Controls will be placed in the vicinity of jumps but there should be no reason to go on the jumps.
