Limestone north of concrete

[lancegranite]

Reading my copy of Cascade Companion, Dock Butte is described as limestone cliffs columns and sinkholes. The photo shows only smaller clean boulders.

The views should be good.

 

North of Concrete, south of Mt. Baker

If somone ferret's out some limestone and opens some routes that would be cool. Marcus is a looong drive.

I will read my geologic map to the area.

Chilliwack Valley has, count em, 6 limestone sport routes, 10d-12c, more going up....

NO limestone for BEN!!!!

 

I think Layton may have checked somethign out there a while back.

that shit was marble.

Dock (or Dock's) Butte is known locally as an easy hike to a great viewpoint for the S side of Baker. Access is off the Schreiber's meadow/Wanlick Pass rd, stay to the L (do not go to Schreiber's), then L again at Wanlick p. on the Blue Lk rd. I do not know any climbing history on it but from flying over it I would say it is not exactly Yosemite-esque. Blue Lk has a black fly rep as I recall. I would be a bit surprised to know that it was limestone, as I thought those deposits were concentrated near the lower end of Lk Shannon.

I think it was limestone that had lost its marbles.

The flies ARE horrible at Blue Lake. I don't remember Dock Butte as an area that I thought of exploring for climbing possibilities. If I remember correctly there were no good looking lines and the rock wasn't that hot.

I wonder what made you think of this?

 

Maybe it's already been found...

geology.

 

look for the marine sedimentary rocks. pukey brownish green color.

You are right, there is significant limestone up there;

after digging around in my cerebral cortex, I also remembered the following:

 

Halliday, W. R., 1963, Caves of Washington: Washington Division of Mines and Geology Information Circular 40, 132 p., 9 plates. (out of print)

 

I recall reference in this to one of the longer limestone caves in Washington being located W of Dock Butte/Wanlick pass. (I don't own this pamphlet - probably read a copy at the FS years ago). So I was wrong in questioning Dock Butte's dolomitic heritage! No one can accuse me of being a geologist...

Limestone isn't extremely common anywhere in Western Washington. There are a few deposits that were mined near Granite Falls. Those were abandoned in favor of ones found on Whidbey Island, I believe.
