00:00:00
this is pretty soft ground it is uh in terms of you know when you leave a a footprint you know something on the
00:00:07
ground it's it's really not the impression isn't that deep right well it's it's um this is decomposed granite and it is
00:00:15
fairly easy to to leave an impression you can see several uh places in here and I made this one just now and you can
00:00:21
see just from the bottom of of my boot it uh it picks up the same pattern that's in there so it's it's fairly well
00:00:29
preserved in this dirt and if you uh get a good impression one that isn't kind of
00:00:34
disturbed by grass and and other things uh there's a lot you can learn about it and one of the things you you try to
00:00:40
look for is maybe something like a rock that's stuck inside the tread pattern that would show up as a dent in there
00:00:48
what does that show you well then if you have a suspect shoe that has a rock in it and the impression has that same dent
00:00:56
in it then you can say that impression was made by that too because the Rock is in it it's not an impression of any kind
00:01:03
of right and it's the same with a tire because uh maybe a rubber knob is broken off the bicycle tire or there's a rock
00:01:10
stuck in there any kind of a defect that's in the tire or the shoe impression um makes that a unique
00:01:17
impression if you don't have that then you can't say that impression was made by that boot only a boot similar to it
00:01:25
correct
