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