Grand Canyon 2010 from Uncage the Soul Productions on Vimeo.
TL Report: Check out this amazing short video of the canyon above. It's only 2 mins but the effects are incredible.
It was nice to see a bunch of people on the trip at the house this holiday season. I think we've set the menu; however, I have a few questions to ask Moenkopi about food preparation before it's finalized. Simple and easy is better than complex and time consuming. I'd like us to spend as little time as possible in the kitchen. Not only would we rather be out exploring/hiking, but the heat will be such that we don't want to spend a lot of time leaning over a hot grill/dutch oven/etc. So, no aforementioned dutch oven meals and no baked deserts. Also, simple eat and go breakfasts will be the norm. I must say it's hard to contemplate the heat when I'm looking at 11 inches of snow outside right now!

| Blacktail Canyon |
Mileage This Week: River Mile 119-121.At River Mile 120.6 we'll reach our camp for Day 9, Blacktail Canyon. My goal is to combine our camps with awesome hiking opportunities as much as possible, and this is one of those opportunities. From camp, there is easy access into Blacktail Canyon which is well know for it's amazing acoustics. If anyone has any musical talent, this is a great place to demonstrate! This narrow slot canyon is made of beautiful layers of Tapeats Sandstone, which is a favorite among river runners. Martin and Whitis's river guide states "The hike is really short, about 1/2 mile round trip. From camp, follow the path leading into the drainage. Walk up the drainage and you will quickly enter a deep Tapeats slot canyon. You will have to climb around or wade through a few pools to reach the chockstone in the back of the narrows. There is a permanent trickle of water here. If you look, you'll see the roughly 550 million year old Tapeats Sandstone resting on top of the 1.6 billion year old Vishnu Schist. You can touch both rock layers and span over one billion years of mission geological time, this is called the Great Unconformity" (more below on the great Unconformity).
At Blacktail Canyon the river takes a turn to the East and runs straight, and mostly flat for 2 miles. This section is called Conquistador's Aisle and is named for the Spanish explorers who were the first Europeans to see the Grand Canyon from it's rim.

| Tapeat's Sandstone |
GC History: Tapeat's Sandstone - This layer averages about 545 million years old and is composed of medium-grained and coarse-grained sandstone. Ripple marks formed by ocean waves of an early Cambrian sea are common in the upper layer. The Tapeats is similar to the Redwall in that it forms a barrier between upper and lower reaches of the Canyon that can only be traversed where a fault has caused its collapse. The color of this layer is dark brown and it contains numerous fossils of sealife.

| Hands spanning 1.2 billion years of missing time - The Great Unconformity, Blacktail Canyon |
A "unconformity" is a geological term that describes a gap in the geological record in a body of rock.
Powell, who, besides being a pretty kick ass explorer, was also a noted geologist. When he visited Blacktail canyon, Powell recorded a rather large unconformity in the canyon wall. He dated the Tapeats Sandstone (which is the most distinctive feature of the canyon) at about 500 million years old. However the Vishnu Schist rock directly below the Sandstone was much, much older. It dated to an astounding 1.7 billion years old. This represents a gap of almost 1.2 billion years in the rock record. Put your hands on the Tapeats and another on the schist and you'll span over a billion years of missing time, called the Great Unconformity.
Equipment/Camp/Info Check: Organizational Philosophy
I read this on the rafting GC wiki for River Runners For Wilderness. Something to ponder....
What is the philosophy of your trip? Is this a trip where your meals are so elaborate that you’re washing dishes in the dark? Is this a trip where everyone competes to be the last one to breakfast every day and the last one to get their gear down to the boats?
Or, is this a trip where when you get to camp, everyone helps unload the rafts (all of them), then helps set up the kitchen first so the cooks can start cooking, and only then, heads off to set up their personal camp. Is everyone Looking for ways to help in camp so that everyone has more time to play during the day, thinking Dawn is the best part of the day, and you had better not sleep through it? There's no right or wrong answer here, just asking.
The trip is 16 to 25 days long or more. You can spend it drifting with the current, or taking long side hikes, or relaxing. Or you can spend it poorly organized, drunk every night, sleeping in every day, and rowing downstream to make up time. The choice is up to the collective karma, with tone-setting by the trip leader. The point is, to minimize on-river conflict, it's important that everyone has the same sheet music and can play the same song, all trip long, whatever the song may be.

Bill has written a blog entry on trip philosophy for next week's blog. Have a great week everyone!
Next Deadline: Final trip balance is due February 15th.
