Taken from blog post http://redleafz.blogspot.ca/2013/07/joggins-nova-scotia-june-2013.html Being on vacation meant being on the road, looking for rocks. That also meant that during that week, I had to make at least one stop at Joggins, in the wet province of Nova Scotia, where the bees shoot flames, and.. ok, lets move on. Here's a few photos of my trek down the beach. Like always, be mindful of the tides. Not knowing when high tide comes in could spell trouble as exit routes are not easily found. So you'd end up stranded for a few hours, so really not recommended to stick around when high time comes around. Sand nodule containing plants The sand nodules that I found on the beach are extremely hard and those I came across contained mostly plants, like the one I found already cracked on the photo above. Some of them were covered with pyrite (fool's gold). Trackways or sediment deformation? Lots of new plants, especially calamites (some whole) A lonely fern Found the other print of the lonely fern Got to the coal mine shaft and was surprised of how much had eroded away in a matter of weeks. Parts of the top of the shaft had collapsed then washed away, leaving a bigger gap. You could smell sulfur, and it smelled like heck! Mine shaft pic taken last year (left) and this Summer (right) View of inside the shaft Stigmaria ('tree' root) Calamites in situ Sigillaria imprint I was surprised that this time around there were not many trees. I've found one partly buried in scree, and another (mostly flame scarred) loose on the beach. There was a lot of material that had come loose, but the tide had managed to carry and spread these all over. This spot is usually hard to resist when talking rock trip. Every time I come down here, I end up seeing an ever changing scenery. If you're ever in the area of Joggins, Nova Scotia, stop by. Its worth it. Cheers! - Keenan
redleaf101 posted a topic in Nova ScotiaHere'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!
redleaf101 posted a topic in Nova ScotiaTaken from my blog: http://redleafz.blogspot.ca/2013/04/red-rocks-mcgahey-brook-cape-chignecto.html I've been catching up on a lot of past trips I made in the Maritimes that I didn't have time to post on my blog. One such trip was a rockhunting trek in Nova Scotia in the Advocate Harbour area, West of Parrsboro. Site (circled in red), Isle Haute (bottom left) The topography of the southern Chignecto region is very faulted, showcasing the collision of this part of the continent with North Africa some 400 million years ago, forming the ancient Supercontinent Pangaea. The Carboniferous strata of this regions has been folded and faulted in spectacular fashion, neighboring Jurassic (Early) age basalts from North Mountain, which you can see at Cape d'Or and other locations along the Minas Basin, and rhyolites in the West (ie. Spicer's Cove). Cape d'Or is especially known for its natural copper deposits, once mined in the early 1900s. 1- Actual Location (C-H Carboniferous, Early - Horton Group) CC - Carboniferous, Late - Cumberland Group (ie. Joggins) 2- Cape d'Or, Copper deposits, basalt lava flows, major fault 3- Jurassic, Early - North Mountain basalts (various overlapping lava flows) Isle Haute, composed mainly of basalt (Jurassic) Since the last ice age about 11,000 years ago, the area was uplifted. The land rebounded, leaving raised beaches on top of the cliffs with layers of glacial till. Because the region was involved in this tectonic tug of war, whatever fossils found in the rock has been worked mostly beyond recognition. There are some rare fossils that escaped this calamity, but they are very scarce indeed. Sandstone and other types of sedimentary rock had been metamorphosed, pulled apart and pressed, warped, and molded. Beading, sandstone under tectonic stress Tremendous pressure applied to these rocks introduced minerals such as quartz (quartzite). The shales and mudstone are practically pulverized, ground into a very fine material, resulting in this dark sand all over this beach. Glacial striation for fault scarring? Horsetail (related to ancient club mosses, lycopsids) Nice folding! Folding and faulting Sedimentary strata changed under incredible stress Morphology drastically being modified in several episodes This area is very fascinating and exciting. Here is a place where you can witness the continent being pushed around and shaped over and over during a very long period of time, in various ways, due to harsh and extreme forces exerted by the tectonic activity at the time of continental push and separation over 400 million years. The scale of it is amazing on the grandiose scale to the micro level of change. This shows that rocks can be very malleable under great stress. What doesn't bend, eventually breaks. Cheers!
Taken from my blog: http://redleafz.blogspot.ca/2013/04/birch-cove-west-beach.html One of the curatorial walks organized by the Fundy Geological Museum (FGM) took us to Birch Cove/Raven Head (Candidate Wilderness Area), North of Cape Chignecto Provincial Park. Here's a description posted by the FGM about the area: The province wants to designate the area as a Candidate Wilderness Area. But when we got to the site, we encountered something that could jeopardize the efforts to make it happen. I'll elaborate a little later. The other location that we visited after Birch Cove was West Beach, not too far West from the first location. Our first trek didn't take long and we had time a plenty before the tides came back, so we took the opportunity to head over West Beach. Here's the description posted by the FGM on their website for Apple River / West Beach: Both sites are part of the Carboniferous Cumberland Group (Late Carboniferous). This area doesn't show the same type of disturbance experienced further South near Cape Chignecto Provincial Park, which shows signs of faulting and folding. Birch Cove (1), West Beach (2) To get to Birch Cove is to drive West of Parrsboro (easiest way to get there) via Apple River Road or by driving South from Joggins on Shulie Road. Getting there is tricky if you don't have a guide that is already familiar with the area. The roads are dominated by dirt roads used by tractor trailers hauling wood. The roads are extremely bumpy and dusty, making the drive a bit of a drag. We parked the cars in a safe area and started down some semi-wooded trail. When I say semi-wooded, it means that the foliage is only a few feet in thickness on each side. The rest has been clear cut, and the landscape is just a poor sight to see. The province wants to make this area some kind of protected nature reserve, but there's not a whole lot remaining. Sorry sight indeed After a little pause to contemplate the area, we proceeded further down the trail where we got into a wooded area. Walking down the trail to the beach Raccoon tracks We made our way to the beach and it was nice, compared to the sight we saw up the trail just before. Water environments are the dominated feature when looking at the sediments that compose the cliffs in this area. The traces of past ice activity on a major scale is also apparent on the topography of Birch Cove. Sand stone cliffs mixed in with layers of conglomerate, marine sediments, topped by glacial till and raised beaches. Ken Adams (left), Kerr Canning (center), Matt Stimson (right) Warm enough for a swim =P Birch Cove is a nice site. Not a lot of fossils around but nice to see the diverse topography of the locality, which was a major factor in the region's local economy for many years. Several locals within the past two centuries had settled in the area and erected mills, using the water flowing down the Apple River. Kerr, which was part of the expedition, had found several artifacts from the previous century of settlers that had since abandoned the area a long time ago. He showed us remains of some of the settlement in the nearby forest. What remains are several sandstone blocks from various foundations. One of the old foundation After wandering in the forest for a little while, we came out the trails and hopped in our cars to head over to our second destination. West Beach is a few kilometers South-West of Birch Cove. The cliffs in this site have strata that are more familiar of the other sites such as Joggins. Also similar are some of the fossils that we found in this area, especially in the coal-bearing sections. Tree in situ The tree in the picture above shows the base of the tree with two of its 'surface' roots radiating out. Tree roots with root hairs Tetrapod footprint Overall it was a good trip. I had already been in the area before but further South at Spicer's Cove (which I suggest everybody go check!). The drive up and down the rolling hills by itself is worth the trip. One can spend the whole day in that area and come across a very diverse topography. Cheers!
