Next Hike

The next hike will be on Saturday, 6th August.
We meet at the Ballpark in Gillies Bay at 10:00aM.

Last week we had a lovely clear sunny day, dry and not too hot although with quite a strong gusty wind that meant it would be best to stay out of the forest as much as possible.  We drove south on the Davie Bay Rd. to Eagle Creek then turned left and headed up towards Thompson Rd.  Part way up the road becomes quite steep and this gradient proved to be a bit too steep for one of the three vehicles in use that day. Not in the least perturbed the owner quickly turned it around and speedily completed the narrow steep section — in reverse.  Nice work, Brian!  The walk along Thompson Rd. was very pleasant and we were glad to have some shade trees on top of Thompson Bluffs where we ate lunch.

My photo this week was taken on a recent hike along the shore north of the Sandbanks and shows an unusual boulder that caught my eye next to the logs at the edge of the trees. This kind of rock is created deep below the surface of the earth when a molten magma, light in colour in this case, forces it's way into a solid rock quite dark in colour.  Some broken fragments of the dark rock got caught up and carried upwards by the liquid rock which eventually slowly cooled.  The resultant rock can be called a breccia as the smaller peices are angular and not rounded as they have to be to give a rock the name conglomerate.

This unusual beach boulder is an example of a light coloured magma with fragments of dark brecciated host rock.
