Hey there
it is 2 days before Christmas
and David and Sam and I decided it was a good idea to go out on the beach rock hunting
so
it's
they're calling this a blizzard, although we're only supposed to get a couple inches
of snow today, but it's
what's the wind, 45 mile an hour wind gusts?
so
we don't know if there's going to be too much ice on the beach, but we're going to
give it a try
and we thought we'd film the intro here, just because I don't know if you're going
to hear anything for the rest of the video because of the wind, but
should be interesting
everybody excited?
oh yeah
been looking forward to this
well this isn't looking too promising
all the ice is washed up on shore here, but we can see rocks
right along this little spot here
question is, can we chisel them out of the ice or not
(Sam) cladapora back there
(Rob) oh was there?
(Sam) yeah
(Rob) okay, we're going to go look for cladapora
there it is
it's going to stay right there too
what'd you find, Sam?
(Sam) bit of mudstone, thought it was banded chert, but it's mudstone I think
(Rob) yeah it's pretty mudstone
(Sam) yeah
you know
it's really not the temperature, it's the wind
(Rob) there's our first puddingstone
somebody kick it
(laughter)
okay
I guess that one doesn't want to come home with us
(Sam) seems like we could
not a bad one either
I got it loose
(Rob) Sam hit it with another rock we got up on the beach farther
not a great rock though
(Sam) sprinkles
(Rob) okay, it wouldn't be a Michigan Rocks video without
a stripey rock
Sam just pointed out another stripey one
it's coated in ice
oh, Petoskey stone
okay, get it Sam
I have a rock hammer
in the garage at home
(laughter)
nice
nice retrieval
a nice piece of unakite
looks like David's spotted something maybe
(Rob) what are you after, David?
(David) I found this
banded something, not sure if it's mudstone or
chert, looks interesting though
(Rob) probably mudstone out here, there's a lot of it
that came out fairly easily
why don't you
warm up the ice with your tongue?
(laughter)
(David) it's neat with
I mean if you look at it from the side
you see that it's all parallel layers
different colors
indicating a change in the environment, the depositional environment
but then when it erodes in a different
the different levels kind of show up differently, kind of like a topographic map
(Rob) yeah those are always fun rocks to find, I really like those
you still have that one,
you shined up one last year, didn't you?
(David) oh yeah that's still sitting
right up on
the windowsill in front of my sink in the kitchen
near that littlie bowl you made me for Christmas
(Rob) oh okay
what you going after, Sam?
(Sam) puddingstones
(Rob) I saw it move (Sam) yeah
That's pretty good (Rob) yeah it's okay
(David) I found a shin plate
(laughter)
(David) +5 protection
(Rob) nice little Petoskey
(waves crashing)
(Rob) Sam's hunting his footprints
what'd you find down there?
(Sam) Petoskey stone
(Rob) oh yeah
so there is water under here
of course we're standing in it
What do you have, David?
(David) looks like I found a puddingstone
(Rob) that's a really nice piece of jasper right there, it's got bands
(David) yeah, got bands in it
(Rob) yeah, there's actually quite a few
lot of white
(David) yeah
what's nice about these puddingstones is
so they're, it's a metaconglomorate, which means that
it needed heat and pressure to
form like this, nice
nice heat
the
something we're missing right now
(laughter)
(Rob) it's fun to think about though, isn't it?
people are always telling me how calm and relaxing the sound of the waves are
well let me tell you, right now
between the wind and the waves, it's just loud out here
super windy
(gently lapping waves)
So David, am I correct in saying that glaciers brought a lot of these rocks here?
oh yeah, certainly
so
all of Michigan, down to
I think southern Ohio was covered with glaciers
mile thick of ice
and as they
they progressed, the glaciers, they flow
like a
like a river under all that
weight and pressure, the ice
performs plastically
and as they would flow, they would scrape across the ground and bring all sorts of
different rocks and
sand and sediment and clay from
from Canada
so that's why we have such a wide variety of rocks here
(Rob) so the reason I asked you is, are we in danger of the glaciers taking
the rocks away today?
on a day like today I'd be wondering that as well
(Rob) it seems somewhat glacial out here
that's Gowganda Tillite
Petoskey stone there
nice cladapora
really big
nice
(Sam) well it looked good on that side
but it's pretty plain on that side
(Rob) you found a shelter, huh?
yeah!
(Rob) it really does cut the wind (David) it does, yeah
so I figure this is where we'll set up our sleeping bags
(Rob) yeah, you can set up your sleeping bag
oh yeah, that's
Petoskey stone
(David) yeah, it
might be a decent one
(David) it's hard to tell (Rob) you have your
your rock hammer?
(Rob) oh, Sam's got one
might have to thaw that one out to see into it
yeah, I mean, looks decent
(David) yeah
(Rob) broken
that doesn't matter
(David) hang onto it
(Rob) well, now that it's all thawed out, what do you think?
(David) well, looks pretty good
maybe not right now, but if I get it wet again
nice pattern
(Rob) that's going to be good
both sides actually look pretty good
you can grind through some of that stuff sometimes, if there's bad spots
that side view's going to be kind of cool where it's broken there
(David) are you thinking that we'll
polish this part too, or just leave it rough?
(Rob) it's up to you, I was thinking polish it, but you can do it however you like
(David) yeah, I can give it a try
(Rob) alright
polish her up
(wheel grinding)
(Rob) how's it coming along after the first wheel?
(David) oh, pretty good
pretty good
there was
a few holes around, big one over here filled with
some sort of rusty silty
stuff, so I had to take it down quite a bit
but
I think it's looking pretty good
(Rob) that's going to be a nice one
I really wasn't sure on the beach how this one was going to turn out, because it
looked pretty rough
(wheel grinding)
(David) alright, so
just finished up with the second wheel here
that was to get out any
major scratches left from the first wheel, and
it's looking pretty good
(Rob) all dried off, so that we can
see, you can see the scratches a lot better that you missed if you dry it off
(David) yeah
(Rob) I kind of wonder if you should take, now that we're looking at it, if you should
take more of those little white spots out, sometimes those stay if you
if you don't take them out
(David) okay
so just a little bit on this wheel before moving on?
(Rob) yeah probably
but I think it's coming along really nicely
they never look very good dry, but
that'll look really good when we get through all the wheels
that's a nice one
(wheel grinding)
(David) here it is after the third wheel looking even better
(wheel grinding)
(David) on the last wheel I can actually see it getting better, this one I can feel
as I'm polishing it, getting more and more slippery
(wheel grinding)
(David) alright
I think it turned out really nicely
I'm happy with that
(Rob) you should dry it off and see how it looks dry
(David) oh, this is dry
(laughter)
(Rob) it's a good polish when it looks wet when it's dry
(David) yup
that's exciting
alright, this is when we have to go back outside
(Rob) yeah, back to that cold beach
(David) alright
(Rob) pretty rock
(David) well this is bringing back memories
(Rob) yup, the ice balls are here
we were just talking about these this morning, we saw them
saw them a couple years ago, when we came out around Christmas time
look at them floating out here
oh there's a puddingstone
Sam, can you remove that
chunk of ice from my way?
(Sam) this one?
(Rob) yeah, see it?
that right there
just that one spot I guess
that's a really nice Gowganda Tillite there
I guess that's not moving
we'll just peek at it
well those are going to be hard to get off
(Sam) yeah
well, the walk out was
a lot nicer than the walk back
we walked with the
wind to our backs on the way out, now we're
now we're paying for it
you're telling me
found a couple ice volcanos, these just formed since we've been here
(David) that one's really spewing
wow
well who had fun
I did
that was a good time, cold on the way back, but fun
yeah
so
what'd we come back with what, five little rocks or something?
and memories
and memories, yes of course
alright, so
we'll link the video with the big ice balls from a couple years ago here, so you
guys can check that out if you haven't seen it, and we'll see you next time!
