Deek's Heaven

Tyler preping the pack in the trailhead parking lot just off the Sea to Sky at Porteau Cove, 50km (30mi) from Vancouver.

Radu soaking up the views at the 6km (3.7mi) mark. The trail wasn't nearly as well kept as the Garibaldi hike we took earlier this year, but we also didn't see anyone this time around.

Radu and Tyler looking out towards Horseshoe Bay and the Sunshine Coastal Mountains.









The campsite viewpoint; to the right is the hut and left, the outhouse.

Awww, the hut, rustic yet still very civilized with a checker board carved into the table with tiny wood cookies as pieces.

The hut was built in the 90's for mainly winter use, or by lazy college kids in October. The ladder on the left goes to a cozy little loft.



Outcrop with a great view of the area, from here we headed up the scree....

The only sketchy part of the trip was climbing around all these loose rocks.

But well worth it

Gambier Island and Horseshoe Bay



Tyler and Radu



Looking north towards the Tantalus Mt. range

I google earthed the area we hiked and the town in the picture is called woodfibre, silly Canadians.





North again towards the Tantalus range











Awww morning light is the best






Tyler posted









View from the campsite

Outhouse view

I cam almost hear the snap, crackle and pop











Frozen pond in the morning





The outhouse









Deek's Mountain, all the good views we got were from those big rocky cliffs

Tyler taking the final steps

Then a sun set drive on th Sea to Sky back to Vanny

More than a billion years ago, the North American continent began to split apart along plate tectonics. Molten lava upwelled into iron-rich lava flows throughout the Midcontinent Rift System, including what is now the Minnesota Iron Range region. These flows are now exposed along the north and south shores of Lake Superior. The tectonic forces that attempted to pull the continent apart, and which left behind the lava flows, also created the Superior trough, a depressed region that became the basin of Lake Superior.

The commonly accepted theory of Agate formation:
The Multiple Solution Deposition Theory

The formation of agates begins with an empty gas pocket or
vesicle that became trapped within cooling lava. At some point after the lava cooled and hardened cracks developed connecting the vesicles and produced a network through which ground-water flow. The timing of when the ground-water moved through the lava flows could have been shortly after they were deposited or millions of years later. As water moved through the lava pile silica was dissolved from the host rock and carried as a solution into the vesicles.
Once the silica-rich solution enters the vesicle, it fills the cavity which allows a thin layer of fibrous quartz called chalcedony to form on the inside surface of the cavity. This initial layer becomes the first band of agate in its formation. At some point, negative fluid pressure sucks out the solution leaving the cavity empty except for the thin layer of agate. Subsequent events of positive and negative pressure fill and empty the cavity. During each event a layer of chalcedony or agate is deposited that progressively fill the vesicle forming the agate.
