Wayne Ranney leads a great trip to the Trail of Time at the South Rim

On a windy and cold last Saturday Wayne Ranney lead the club on a great trip through the Trail of Time at the South Rim. The trail is a hike where every million years is one meter. There are brass plaques every 10 million years. We hiked all the way from the Precambran to the present-about two billion years.


Rock samples taken from all of the formations in the canyon are on pedestals at the appropriate place on the trail.



It was a great trip and a great way to view Geologic Time.

Geo Field trip to Drake Cement

Friday we had a good short Club Field trip to the Drake Cement Plant. 19 people went on the trip to see the impressive operation and the Redwall quarry where they mine the limestone which they cook into cement.
