Hiromi Posted November 29, 2003 Share Posted November 29, 2003 So what is conglomerate rock all about? I was recently in Monserrat and people were climbing all over this stuff. I've never really seen it before, & would be afraid it would crumble. Anyone been climbing there or somewhere like it? Quote Link to comment Share on other sites More sharing options...
daler Posted November 29, 2003 Share Posted November 29, 2003 It can be very solid or really crumbly. I just got back from Spain as well and climbed at Montsant, which is very close to Siurana. Some of it was great and some was crap. I definately did not like it as much as the pure limestone at Siurana. Dale Quote Link to comment Share on other sites More sharing options...
Bug Posted November 29, 2003 Share Posted November 29, 2003 It is an indication of how addicted to climbing some people are. Pinnacles north of SF is conglomerate. Marginal. Quote Link to comment Share on other sites More sharing options...

Same rock at Maple Cayon UT and Hope Boulders BC and Pinnacles Calif. The difference is the solidity of the matrix material that holds the stones together. On conglom with a quartzite matrix you can reef on 10% attached cobbles and they will hold where if the conglom is matrixed with weak sandstone or calcite they will pop with impunity.

catbirdseat Posted November 30, 2003 Share Posted November 30, 2003 Isn't the rock at Fossil Rock a sedimentary conglomerate? Quote Link to comment Share on other sites More sharing options...

If I am that close to the valley, I will not be climbing choss. Quote Link to comment Share on other sites More sharing options...
Peter_Puget Posted December 1, 2003 Share Posted December 1, 2003 Pinnacles is also volcanic in origin. It also has some great climbing! Quote Link to comment Share on other sites More sharing options...
Dru Posted December 1, 2003 Share Posted December 1, 2003 From now on anyone making an assertion as to provenance of cobble-filled rock, please include reference to published geological study of area covering rock you are citing. These unsubstantiated Internet assertions as to volcanic vs. sedimentary provenance are devoid of verifiability. Quote Link to comment Share on other sites More sharing options...

Peter_Puget Posted December 1, 2003 Share Posted December 1, 2003 Some of the sandstone pinnacles at Swauk Pass have some incredible loose pebble bands running through them. The area makes for some great day hikning and occasionally fun climbing too. Quote Link to comment Share on other sites More sharing options...

If I can get to Pinnacles it would be easier to get to the valley. Quote Link to comment Share on other sites More sharing options...
David_Parker Posted December 2, 2003 Share Posted December 2, 2003 I've seen that shit on cliffs along the coast. I would be more inclined to use ice tools, but even that would be sketchy. Pebbles and rocks held with mud....echhh! Quote Link to comment Share on other sites More sharing options...
