  1. It appears to me that lava flowed over a scallop bed followed by weathering in the surf - i think some mineralization has occured but i cant be positive. Seems a bit rare to me but i don't know anthing about it. Any information would be helpful. Could it have came from Hawaii
  2. Here's the link to the original blog post: http://redleafz.blogspot.ca/2013/04/somewhere-in-parrsboro-there-are.html A few days ago I drew a map of the West Bay/Cape Sharp area South-West of the town of Parrsboro, Nova Scotia. I had wanted to check the Jurassic age basalt cliffs of Cape Sharp and poke around a bit to see if I could come out with anything. On the cliffs on each side of Cape Sharp are Carboniferous sandstone cliffs which displays a fascinating record of trackways, especially those of tetrapods. I had marked on my makeshift map where the location of a possible access point to the beach would be. If that wasn't the case, I had a plan B, set by driving back towards Parrsboro and finding an access point via Partridge Island. I woke up Sunday (April 14th) morning and it was snowing. I said to myself: "Rain, Snow, or Shine, I'm heading down!". I hit the road at 7am that same morning. The temperature kept at about 0oC Celcius so the road conditions were pretty decent. The snow was melting as soon as it hit the pavement. I had checked the forecast the night before and they had called for higher temperature and a break in late morning. That was good enough for me. I got to the road leading to the supposed beach access by driving a red, muddy, slippery road with my Rabbit. My car is usually gray, but not this morning after my trip down here. I parked the car, got my gear, and headed down the path. Getting down the trail was somewhat annoying. Big trees had fallen at numerous spots and sometimes that meant I had to crawl in the mud or hop on the logs. I'm barely 5'2", so yeah it wasn't a pretty picture. Cape Sharp behind the snowy haze I got to the ledge of the cliff and there was somewhat of a 'trail' going down. It zigzagged a bit but the last 15 feet were just muck and loose sediment. I don't think that if I went down I could get myself back up. I tested the trail halfway and tried going back up. The face of the cliff was so loose and slippery that it took every ounce of strength in me to make it back up. There was no other spots to go down so, defeated, I made my way back up the steep trail. I exerted myself trying to go up that I had to lie down for a few minutes, fighting waves of nausea. During that episode I somehow managed to gash my hand pretty good. Wet, muddy, and bloodied, I sat my sorry in the car and drove to Plan B. West tip of Partridge Island There was no way that this rock trip was gonna be in vain, so I found myself taking the beach road behind the Ottawa House down West Bay Road. Last time I was here was in 2011 so my memory was a little bit hazy. I drove down the sandy road and after dodging or ramming through some major olympic sized pools of water, I managed to park in a safe area. Dirty rabbit! The tides were coming back slowly so I had lots of time to stroll on the beach. Everything was wet so I was curious to see if I could still spot trackways with all the glare. Turns out after a few minutes that I could, and I managed to spot some old tracks and some new ones. The cliffs are put at about Late Carboniferous, and are part of the Cumberland Group - Parrsboro Formation. The layers show an environment alternating between wet and arid, indicated by layers rich in river biota with surrounding vegetation, and the next indicating dryer conditions. Mud crack features The next few photos show a series of trackways and close ups of the ones I managed to spot. Multiple sets of tracks Tracks running horizontal Set of tracks, evenly spaced, with drag mark running along the center Close up of one of the indentation (from the previous photo) No clue at the present of what this is In a section that was protected from the elements, I took the time to take a closer look at some of the rippled surface and found some nice tiny tracks skipping on the surface. Each mes/pes are about ~1cm, running in several directions. Folding where two major faults intersect. The rock is strained and the strate disappears under a thick mix of glacial till, only to reappear a few hundred feet further West. Some trackways to be found, but mostly deformed and barely identifiable. This trip ended up being a very good one. I was able to get to see a few things I haven't seen before, and new data to incorporate in my ever evolving map of the area. Shows that its nice to prepare a litte in advance so that you're not left in a lurch. To finish a good trip in Parrsboro, I had to stop at my friends place, Doug and Jackie's of course! Stayed a while and talked rock. I managed to get out of town with two gorgeous pieces to add to my ever increasing mineral collection. Here's their site: http://www.amethystboutique.com/ On this note, I leave you to your musings. Cheers!
  3. Taken from a June 2011 trip - http://redleafz.blogspot.ca I've since gone to that site so many times I can't remember. This location is as rich in fossil material as it is in minerals. Enjoy! Wasson Bluff - Parrsboro, Nova Scotia Every year the Fundy Geological Museum (FGM) hosts curatorial walks of the many sites located in the Parrsboro area in Nova Scotia. Saturday June 11th the FGM organized a curatorial walk of the Wasson Bluff located a few minutes east of Parrsboro, on Two Islands Road. I had gone only once before last Summer. I was happy to go back as I wanted to find out all the information I could get from Wasson Bluff. Wasson Bluff is a very special place, as the earliest dinosaurs have been discovered in this area. This area has seen the smallest dinosaur foot prints ever found, some of Canada's oldest dinosaurs ever found, and important signs and clues of the ever changing landscape and makeup of the Earth. The curatorial walks are free, and that weekend being tourism week, the admittance to the Fundy Geological Museum exhibit was also free. Me and my friend Craig, along with some other fellas had some time to spare before the walk, so we checked it out. It is well worth it as they have a lot of interactive games and displays, and wonderful specimens on display. By the time we were done the museum, there was still about an hour left before the tour, so we asked for directions on local eats. The friendly staff helped us by pointing out local restaurants not too far in town. We opted for one that was at the end of a street next to the museum on Pier road. The tiny restaurant, the Harbour View, was a home cooking style seafood restaurant and it didn't disappoint. The food was great and the service was good. View of the bay from the restaurant. Wasson Bluff is located further west of the FGM on Two Islands road. It takes a little bit less than 15 minutes. Here's a few pics from the walk: Getting ready for the hike. My friend Craig on the left. The welcome sign at the Wasson Bluff entrance. Hopping down the steep trail. Easier down than up as I would learn coming back up. Finally on the beach! View of Clarke Head. The tip of the cliff is darker basalt/volcanic rock. The gray/greenish-like part of the cliffs is gypsum/salt-like sediments, remains of bodies of water that vanished a long time ago. From there to where I was standing were the different faults and strata that make up the general landscape of this part of Wasson Bluff. Ken Adams, our interpreter, and also the FGM's curator. (Two Islands in the background) Close to the beach entrance you'd get these strata of sandstone and mudstone. These look similar to the carboniferous strata you'd encounter at beaches like Joggins. The sandstone show animal tracks and natural weathering. Ichnofossils (animal tracks) made by ancient animals. Cliff made up of volcanic rock. Sedimentary mud filled with clastic basalt rocks and bone fragments. Clastic basalt fragments in sedimentary silt, signs of the work of continents moving apart. Bone fragment in sedimentary matrix. The picture above seem to show sedimentary mud that would have squeezed in fractures of this volcanic rock, creating the look that we're seeing here. If I remember right, magma would have solidified (could have been underwater), and at a later period silt like mud would have made its way, filling any cavity it could propagate into. The green algae show the level of the tides. Bone fragment in Triassic age rock. In the background you have your greyish volcanic rock. In the foreground you have a mix of wind blown reddish sandstone to other types found in aquatic environment. This is the start of what they call Wasson Bluff, famous site of the many dinosaur bones, some deemed at least the oldest in Canada. The sandstone that bear the multitude of bone fragments are usually the ones that show clastic basalt, as they usually indicate some type of aquatic environment, like watering holes. From what I can remember this would have been a valley where animals would make their way. Several events happened to have retained the animals where they are, to later be unearthed by scientists. Such remains are displayed at the FGM for people to view. The Triassic rock shows cavities where animal specimens had been found and unearthed. The cliff face changes all the time, so there is always a chance to find something. What I found fascinating is that we have this type of site in our own backyard, at our doorstep. There is always that awe factor where you're thinking, some of the oldest animals have walked where you have walked. The features you can find in the earth, the traces of animals long gone, the pieces of a puzzle that help define the history of not just the locality, but the global picture of how things were at one point in time. I have enjoyed Parrsboro and I'm convinced that anybody that goes there would enjoy it. Cheers!
