00:00:00.450 --> 00:00:05.872
You see all that unconsolidated
lots of boulder, lots of mud, sand, etc.

00:00:05.872 --> 00:00:09.809
from there
up is all up until the soil horizon

00:00:09.809 --> 00:00:13.680
which is right below the tree roots
just well, actually

00:00:13.680 --> 00:00:16.683
even the tree roots are it
this is all glacial.

00:00:16.850 --> 00:00:20.570
till from the last ice age, Wisconsin
ice age, about

00:00:21.688 --> 00:00:24.407
10 to 14,000 years ago.

00:00:24.407 --> 00:00:29.579
But this level here is the 70, about 74
million year old Wapiti Formation.

00:00:29.579 --> 00:00:31.831
And these rocks are part of it as well.

00:00:31.831 --> 00:00:33.266
So that's the situation.

00:00:33.266 --> 00:00:37.937
74 million year old rocks overlain
by a 14,000 year old glacial,

00:00:38.021 --> 00:00:39.656
unstratified glacial till.

00:00:39.656 --> 00:00:42.275
In geology
speak we call that an unconformity.
