What are Hoodoos?
Hoodoos are a specific type of formation that is caused when sediment erodes at different rates due to different types of sediment. The softer sedimentary rock lies underneath a harder rock, and it causes the sedimentary rock to be partially protected. The alternating hardening along with the wind and rain is what creates the strange structure of the hoodoos.

Geological History of Kelowna
In the past, the Okanagan was a very geologically violent place. Numerous earthcaches around the region point to the remnants of volcanoes that once erupted here.
Millions of years after the volcanic eruptions ended, the area was hit by numerous periods of glaciation which ground the volcanoes down immensely and scattered the rock debris around the lowlands.
The cliffs at this site are made of Feldspathic Lava of the Marama Formation. The numerous glaciations and constant weathering have eroded this cliff face and you now see the till (broken rocks) piled up at the base. Apparently this is ideal habitat for marmots.
Although the following relates to hoodoos on Dilworth Mountain, according to Wikipedia, limestone hoodoos elsewhere in the world are formed due to the following:
"Internal layers of mudstone, conglomerate and siltstone interrupt the limestone horizontally. These layers are more resistant to attack by carbonic acid and they can therefore act as protective capstones of fins, windows and hoodoos. Many of the more durable hoodoos are capped with a type of magnesium-rich limestone called dolomite. Dolomite, being fortified by the mineral magnesium, dissolves at a much slower rate, and consequently protects the weaker limestone underneath."
To Log This Earthcache
E-mail the answers to the following questions to me through my geocaching.com profile. Cache loggers that do not send me answers within 2 weeks will have their logs deleted.
1.) Estimate the height of the cliff.
2.) Give me a size range of till particles that you find at the base of the cliff.
3.) Optional: Take a picture of your GPS and the Hoodoos at an interesting angle and post with your log.
