It is one thing to pick up a rock and try to identify it, it
is another to do this with a bit more of an understanding of the various possibilities
of what that rock represents. This section attempts to explain a concept to
be employed as a framework when trying to identify a rock and speculate on
its history and significance. This account is an outline of presentations
made to...
There is perhaps no better place in the Okanagan to visualize
some of the geologic events that have shaped the land than Bear Creek canyon
on the western side of the lake. Most of the major geologic deposits in
the canyon can be seen from a high viewpoint on the north side of the valley.
Deposits and Rock Types
Two major types of geologic material occur. One type is unconsolidated...
Mount Boucherie is a dominant geologic landmark on the western
side of Lake Okanagan in the Kelowna area. The mountain is an erosional
remnant of an extensive volcanic complex that developed after a huge chasm
split open
the Earth’s crust along ancestral Okanagan Valley possibly 60 million
years ago, in early Tertiary time. The first major volcanic eruption witnessed
the...
Introduction
The geomorphic development of the Okanagan Valley, like anything of value,
took a long time. It mostly involves geologic events that are almost impossible
to imagine, difficult to understand and hard to believe. The geologic history
of the Okanagan Valley is discussed in seven stages, concluding with a somewhat
detailed analysis of the events in the last 10,000 years....
