Ridgehiker Posted April 2, 2017 Share Posted April 2, 2017 A nice Spring day and a return one of my favourite areas. Headed out to the Eastern slopes west of Calgary. Begins with a 45 minute bicycle ride along Canyon Creek. Then the physically hard part...an hour or so climbing through the forested lower slopes to get above the tree line. Then another 4 hours diligently scrambling around exploring the area (yellow circle on photo). Although the yellow circle looks small its the size of a couple soccer pitches. Fossils are from under the cliffs. Cliffs have fossil layers but too precarious to access. 5 Link to comment Share on other sites More sharing options...
Ridgehiker Posted April 2, 2017 Author Share Posted April 2, 2017 Quite peaceful place to rest on upward climb. Lots of birdlife and other happenings. Pikas and chipmunks were both doing their own thing 1 Link to comment Share on other sites More sharing options...
Ridgehiker Posted April 2, 2017 Author Share Posted April 2, 2017 Breaking through at treeline. Some of those rocks are car size. 2 Link to comment Share on other sites More sharing options...
Ridgehiker Posted April 2, 2017 Author Share Posted April 2, 2017 The exposed rocks before the steep cliffs are Banff Formation. Earliest Carboniferous (Tournaisian). There are distinct layers climbing across the boulders. The first being tabulate and rugose colonial corals. Genera are 'in sensus lato'...Syringopora and Stelechophylum. 2 Link to comment Share on other sites More sharing options...
Ridgehiker Posted April 2, 2017 Author Share Posted April 2, 2017 Next layer are crinoids. Lots of stems, loose segments in the ground and calyxes in the matrix. I rarely find a loose calyx. First photo Calyx on one piece, stem on another. Another with a calyx impression. 1 Link to comment Share on other sites More sharing options...
Ridgehiker Posted April 2, 2017 Author Share Posted April 2, 2017 Every so often shark teeth in matrix. A variety of genera. These haven't been studied. Some rocks also have scales like these. Shark teeth are hard to photograph in the sun. 1 Link to comment Share on other sites More sharing options...
Ridgehiker Posted April 2, 2017 Author Share Posted April 2, 2017 A layer that contained lots of bryozoa and blastoids in matrix. Some loose blastoids of various genera. Not studied but tentatively assigned to 'Schizoblastus', ' Deltoblastus' and a few others. 2 Link to comment Share on other sites More sharing options...
Ridgehiker Posted April 2, 2017 Author Share Posted April 2, 2017 There's about 80 varieties of brachiopods...they correspond to the layers. Quite a variety of genera. Loose brachs aren't rare but difficult to spot in the rubble....especially when I'm clinging on with all fours to gain traction on the slope. 2 Link to comment Share on other sites More sharing options...
Ridgehiker Posted April 2, 2017 Author Share Posted April 2, 2017 View to the northeast. A falcon landed on the tree a couple times. Likely a migrating Peregrine. It took off every time I tried to take a photo. Link to comment Share on other sites More sharing options...
Ridgehiker Posted April 2, 2017 Author Share Posted April 2, 2017 Across to the east. The same sedimentary layers ( middle of mountain) . I once trekked up that side but took me half a day...I was also younger. Similar fauna found. 2 Link to comment Share on other sites More sharing options...
Ridgehiker Posted April 2, 2017 Author Share Posted April 2, 2017 There is a layer of strange branching squigglies. Not bryozoa or graptolites. I just call them Squiggles. Another rock of enigmatic 'spiders'. 1 Link to comment Share on other sites More sharing options...
Ridgehiker Posted April 2, 2017 Author Share Posted April 2, 2017 Typical 'hash plate' at upper level before cliff. Contains a variety of stuff from trilobites to brachs, bryozoa, crinoids, etc...but never shark teeth at this layer. Now and then a gastropod but they are rare. 1 Link to comment Share on other sites More sharing options...
Ridgehiker Posted April 2, 2017 Author Share Posted April 2, 2017 At the base of some daunting cliff layers. Looks like the top but still a long ways up above these cliffs. Above the cliff are rock layers from the Livingston Formation ( Visean age) 2 Link to comment Share on other sites More sharing options...
Ridgehiker Posted April 2, 2017 Author Share Posted April 2, 2017 Must be lots of good stuff up there. Lots more layers but...yikes... 1 Link to comment Share on other sites More sharing options...
Ridgehiker Posted April 2, 2017 Author Share Posted April 2, 2017 Only a thousand meter drop over the ledge. Ledge is bigger than it looks but still gives me the heebie-jeebies when out there. Carboniferous mountains in the distance. Beyond that set of mountains one gets into Cambrian formations ( Burgess Shale). 1 Link to comment Share on other sites More sharing options...

Ridgehiker Posted April 2, 2017 Author Share Posted April 2, 2017 Time to head down. Yay! All down hill and same with bike ride returning to vehicle. Soon back in the city and watching the hockey game. 1 Link to comment Share on other sites More sharing options...

This is along Canyon Creek. If you live in Calgary same mountain as the ice caves...you can see the caves to the left in the first photo. Photo across at same layer is of Moose Mountain. I think the snow capped mountain in the distance in the second last photo is Tombstone along the Elbow River loop. 2 Link to comment Share on other sites More sharing options...

ynot Posted April 2, 2017 Share Posted April 2, 2017 Looks like a great place to hunt with many interesting fossils! Thanks for the virtual tour!! Tony Darwin said: " Man sprang from monkeys."

CBOB Posted April 3, 2017 Share Posted April 3, 2017 Looks like some good workout collecting. Its got to feel good getting back to the car on those days. Some of those hash plates are just full of stuff. Always like crinoid finds as well. Beautiful place to collect. Link to comment Share on other sites More sharing options...
Darktooth Posted April 3, 2017 Share Posted April 3, 2017 Great report and pics! Some really nice specimens and I love the hash plates! I like Trilo-butts and I cannot lie. Link to comment Share on other sites More sharing options...
Ridgehiker Posted April 3, 2017 Author Share Posted April 3, 2017 There must be a couple million hash plates to look at in that yellow circle area. However, between the physical exertion, trying to keep my balance, and the lighting...just not possible to concentrate for long and focus the brain on minute details. Back home I often wonder what 'Wow' specimens I unknowingly passed by when out fossil hunting. I recall Phil Currie ( A theropod dino expert) telling how he found his best specimen when he dropped his camera and it rolled down a hoodoo and landed next to the jaw...a place he had previously walked by many times.
