Caves and Karst Landscapes
Hidden deep inside old growth forests, students have the opportuity to explore incredible karst landscapes and gain an understanding of how they are formed. We will visit an area of Vancouver Island rich in limestone, where students will measure areas of limestone pavement, view sinkholes where small rivers disappear undergound, and even explore a local cave system, viewing first hand the power of water erosion and solution.
Our studies will include mapping areas of karst, examining rock structures, landforms, solution pits, grooves and runnels. We will investigate the affect of carbon dioxide and solution of the limestone with the resulting caverns and cave passages that form. Students will examine a karst landscape and visit an area where old caverns have collapsed and are now overgrown, showing how the landscape has changed over thousands of years.
In our followup session, we will overlay our study areas with geological and satellite maps and disucss our findings with the group.
