Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Okay, so this is the difference between uh, glacial till,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,which is unstratified,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,and non-glacial till.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,So, hopefully you can see that this uh, gravel here
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,is well-stratified.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,There are a lot of sedimentary features here.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Um, you can see graded bedding.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,You can also see cross bedding.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Maybe I can just sort of zoom in on that.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,So there's cross bedding right there.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Very coarse uh, cross bedding.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,However, the stratification or the horizontal layering,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,the general horizontal here,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,indicates that this is not glacial gravel.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Even though it's approximately the correct size
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,and sorting distribution.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,The presence of sedimentary features
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,as well as uh, the stratification,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,that's the horizontal layering,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,indicated as not glacial gravel.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Okay. I'll try and show you glacial gravel a little later.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,So this is uh, glacial till.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,It is gravel that is deposited by a glacier.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Um, and the identifying characteristics of it
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,is well-rounded clasts,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,however they're not really really well-rounded.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,They are definitely rounded to some extent.
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Um, oftentimes there are striations on each individual clast,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,maybe I can show you that later.
