An angular unconformity is evident between the eroded limb of the syncline and the overlying horizontal younger layers.
An unconformity occurs when deposition of sediment is "not conform" to an ideal continuous sequence of materials that would record time uninterruptedly (given that rocks are our only evidence of past events). Unconformities can be of different kinds, but they all imply that an interval of time is not present in our rock record.
This unconformity is called "angular" because there is an angle between the layers of the lower unit (the limb of the Miocene Barstow syncline) and those, more recent, of the upper unit.
After the layers that now form the syncline were deposited, the area was subject to compression and the layers folded. After the folding, the area was exposed to the atmosphere and eroded. Then new sedimentation started (the upper unit). The time interval not represented in this image is that between the beginning of the folding and the beginning of the new cycle of deposition.
Note the Joshua Trees on top of the mountain for scale.

Day 16: Angular
Inktober
I really want to branch out in posing for a bit. For this particular photo, I took the prompt Angular to give me some inspiration to switch it up. Much like my Photober shoots in 2013, for this one I was bouncing and jumping around to try and get that movement. I didn't necessarily go for angular poses, though that was my first intention, just something different.
I have a few outtakes from this that you'll be able to see on my personal Instagram, @kaldec_
Something else that I love about Photober is that it not only challenges me in shooting, but in editing as well. As seen in my Rose post, I have been experimenting with different types of editing in my photography. I edited this one as if it were going to go on my @kaldec_ Instagram.
Went on a quick photo escapade with Jacob the other day. Originally I wasn't going to do anything like this but I got a little inspired so here is something a little more experimental.
Sunset Newcastle. A whole lot of mathematics going on here. A semi circle inscribed in a triangle, work out what angle A = blah blah blah. This is a view from the Sage theatre -Gateshead, of the Tyne bridge with the Cathedral Church of St Nicholas to the right.
