Matt_Fetcho Posted February 18, 2002 Share Posted February 18, 2002 Went to Banks lake on Sunday hoping the week with temperature in the teens would produce something climbable. Nothing is in good. The top pitch on Zenith looks great as well as a couple of the other routes nearby that I'm not familiar with. The devil's punch bowl is really thin like most of the single pitch climbs up the road. We did climb however, on the column that sits up away from the road. The lower section was really wet, but the second half was good and solid. A few more days of 40deg and warm nights will bring this season to a close at banks. Quote Link to comment Share on other sites More sharing options...
Retrosaurus Posted March 8, 2002 Share Posted March 8, 2002 You can access the top pitch of Zenith from the right via an entablature ledge and then rappelling from the top of the route. This pitch forms some of the best ice I have climbed on in Washington. Beware the ice hanging above. Last year My partner nearly got blasted off that pitch when an immense whistling-missle pulverized on impact 30 feet from me and avalanched on top of him half way up the pitch .

TimL Posted March 8, 2002 Share Posted March 8, 2002 Thanks Mitch. I was just wondering if any ice is formed at Banks? Do you know if much is formed at Lworth? Tim Quote Link to comment Share on other sites More sharing options...

It seems there must be something more about an entablature ledge than just being at the top of the stack. Is it the different structure of the rock? There must be a more technical definition.

The columnar stuff on the lower part of the formation is the colonnade and the upper stuff is the entablature. Quote Link to comment Share on other sites More sharing options...

(I'm not trying to be a wise-cracker here. Just curious.) dave brannon It is my understanding that the variation in cooling between the upper layer and the lower layer of a thick basalt flow provides the difference in structure. The lower part is called a colonnade and typically shows signs of columnar jointing due to shrinkage as it cooled from the bottom up. The upper part is the entablature and its hacked up structure is a result of cooling due to water seeping into the fractures at the top of the flow. That is about the extent of my knowledge on the subject. Quote Link to comment Share on other sites More sharing options...
TimL Posted March 9, 2002 Share Posted March 9, 2002 With the cold weather and all the snow, anybody know if the Banks Lake ice has formed? Thanks for any and all beta. Quote Link to comment Share on other sites More sharing options...

Zenolith Posted March 18, 2002 Share Posted March 18, 2002 Does anyone have more current info on ice at Banks? Seems like it might be in w/ all the cold we've had recently... Quote Link to comment Share on other sites More sharing options...
Paul_detrick Posted March 20, 2002 Share Posted March 20, 2002 It may be cold, but not that cold, day time highs are in the 40's it's just not going to happen at banks this year. Paul Quote Link to comment Share on other sites More sharing options...
Retrosaurus Posted March 20, 2002 Share Posted March 20, 2002 In the large basalt cliffs where multiple flows can be visualized, there is usually a broken up area where the top of a lower flow interfaces with the bottom of the next overlying flow. This is what I was referring to as "entablature" earlier. This structure where succeeding layers meet often forms a system of ledges or overhangs or both at once, often providiing access to upper tiers, especially when a talus slope reaches up to the ledge system.
