The Cameron-Horne context is similar to the Lowlands context, except for the surficial unit which is composed of fluvioglacial sand and gravel deposits (the more permeable component of the Vashon). All hydrogeological units are therefore present, with the exception of the Capilano-Salish and Capilano units. This context is located at the outlet of the Cameron and Horne lakes, in the lowland area. The coarser sediments of the Vashon could be an important aquifer and is expected to be either perched over impermeable Vashon till or in direct contact with the Quadra unit. The hydraulic connection between the coarse sediments of the Vashon and the underlying aquifers is not well understood as no stratigraphic drilling is available. The Mapleguard sediments may not be present at this elevation. |
