Taken from my recent blog post: http://redleafz.blogspot.ca/2013/04/five-islands-provincial-park-2012.html Here's another of my belated posts on one of my trips last year. Me and my buddy Craig went for one of many trips to the beautiful town of Parrsboro, Nova Scotia. From town, we headed East towards the small village of Five Islands, which has a Provincial park of the same name: Five Islands Provincial Park. Islands from right to left: Moose i., Diamond i., Long i., Pinnacle i., Egg i., Pinnacle rock Five Islands Provincial Park is a location that has witnessed several events, including a major extinction. Most of the rocks South of the park, towards Red Head and continuing on to Lower Economy, are of a red sandstone from the Triassic Period. These red sandstones from around Red Head are indicative of an arid, desertic climate. On top of the Triassic rock is a layer that corresponds to the Triassic-Jurassic boundary, sandwiched between Triassic sandstone and Jurassic basalts right on top of it. This Triassic-Jurassic layer is identified by its white sandstone and mudstone. The importance of this layer is that it represents one of the major extinction events that had occurred at the boundary. It is still being studied today. The basalts that top these sandstone layers South of the park and protrude West and created the islands, are of the same found at Blomidon and Cape d'Or. These Jurassic age ancient lava flows and dykes could have been part of an active volcanic network seen all over the Minas Basin. The Old Wife is a result of this contorted, violent past. The islands which dot the landscape are also mostly composed of this Jurassic basalt, and some sections of Jurassic sandstones. "Old Wife", with Moose Island in the background The red cliffs just North of the basalt and separated by faults is of Jurassic age. Dinosaur tracks and other fossils have been found occasionally from either the cliff face, or from loose rocks on the beach. A local by the name of Eldon George had found, among many other wonderful fossils, the smallest dinosaur tracks ever found back in the 1980s at Wasson's Bluff, sandstones of the same age and formation not too far from here. See Jon Tattrie's article. Organic layers within water channel Jurassic McCoy Brook Frm. (left), Jurassic North Mountain Frm. (right) But I digress, as I keep rambling on the technical and less on the practical. We arrived at the park when the tide was going down. We walked down the beach and was met with a thick band of fog that was going out the bay. Lava flows Heading South after searching the beach for agate and fossil fragments, the fog lifted and the Sun came out. We went around the Old Wife and headed towards Red Head. Fault running through columnar basalt Beach made up of basalt and minerals "Red Head", seperating the Triassic-Jurassic Blomidon Frm. (West) and Triassic Wolfville Frm. (East) Triassic Wolfville Frm. red sandstone cliffs Modern day trackways (crab) This area is only accessible at extreme low tide, so the window of opportunity is very small. Getting trapped or stranded is a very highly probable so good planning and looking up the tide charts before heading down this way is an ABSOLUTE MUST! This is one of the places in Nova Scotia that I highly recommend visiting, among other sites of course. =)
From my blog: http://redleafz.blogspot.ca/2013/04/economy-point-copequid-bay.html Back in August of 2012, I took part of a walk organized by the Fundy Geological Museum (FGM). It was in the middle of the week (Thursday August 9th, I think), so there wasn't any tourist or non-employee beside myself. The gang consisted of geology students and staff, led by Ken Adams, the curator of the FGM. Looking out towards Cobequid Bay Economy is located in Nova Scotia, East of Parrsboro in Cumberland County. From Parrsboro, you take the 2 road and head East, past Five Islands Provincial Park. Economy Point has many trails that are beach accessible, but the getting there can be messy with the muddy silt snaking within the bay. View of Five Islands (background) The rocks of this area are part of the Wolfville Formation, Triassic aged red siltstone and desert sandstones, a lot of it apparently sculpted by wind. The bottom part of the cliffs along the bay are of this red sandstone, and upon it rests several feet of glacial till from the last ice age that helped sculpt the area. Moving around entailed hiking up and down huge slabs of sandstone that displayed odd physical features. There are all sorts of trackways and burrows, but there are also structures that none of us could readily identify. Burrows? Plant traces? Toolmarks? Triassic sandstone (bottom), glacial till (top) Diplichnites (such as of a myriapod)? Natural caves Water channel Bird nests in the cliffs The further East we walked, the stranger the physical features would get. Even Ken was baffled by some of the structures we'd come across. Here's a few photos taken by my Blackberry and you be the judge. Can you identify any of the following? Bottom of a tree (?) Tree roots (?) Many of the structures are found on this red sandstone Worm burrows? These holes are so odd. At first I thought they were cavities left behind by plants, but some of these exhibit strange patterns around, looking bizarrely like projectile of some sort. Some of these 'projectile' show patterns and/or direction. Am I imagining things? After a long and hot afternoon, we turned back and made it back to our cars, pondering on what we saw. We were intrigued by what we had found. Was this unique? If not, where else could we find these? Any feedback would be much appreciated! =)
