This thread reminds me of when I was a kid and I got a Rock Identification Kit.
As soon as I got it, I hit the woods by my house and the local parks and had all of the little squares in the back of the list 95% full except for the last 3 or 4 elusive stones that were hard to locate. I got it done eventually, but I've forgotten how much I used to be into nature as a kid. I used to study everything I came across and back then we didn't have the interwebs as a tool. We had to go to the library to get our info.
Fast forward 20 years when I had my little one (she was about 5 or 6 at the time).
She was in the living room frustrated and I asked her sister who was about 7 at the time what was wrong with her who started to giggle. Turns out she had her own little Rock Identification Kit and had her chart almost filled up as well, but was missing out on the last few stones to complete it.
I'm sure that I'll have grandkids someday (that little one is 18 years old and my older daughter is now 20) who'll find themselves frustrated with some chart they are trying to complete too and I'm glad we all have that spirit of exploration and that hunger for knowledge in us all.
Oh, and she (my little one) eventually got that little chart filled out too;
Geology is a fascinating subject. I found out that a Volcanic chert and coal bed nearby, hit the surface for a few kilometres, and held a rare fossilised Insect bed. I went to have a look, and was dismayed to see houses and suburbia on top of most of it. I ended up finding quite a few fern leaf fossils, they are in all of the volcanic chert lying on the surface.......below is some info which helped me learn about the site. I also knapped some arrow heads from the chert.
Because of the apparent frailty of their bodies, and the ability of many of them to fly, insects are thought of being rarely found as fossils. Any mention of insect fossils though, and most people think of insects spectacularly fossilized in amber.1 However, insect fossils have also been found preserved in fine-grained sedimentary strata, including those associated with sequences of coal beds.2
One world-famous fossil insect bed is that found in the Belmont-Warner's Bay area of Newcastle, approximately 90 miles (145km) north of central Sydney, Australia.3 This horizon is about 2 ft. 6 in. (0.75m) thick, and consists of hard, fine-grained tuffaceous chert. It lies some 70 ft. (20m) below the bottom of the economically-exploited Fassifern Coal Seam in the upper Newcastle Coal Measures, and thus is conventionally regarded as late Permian at around 250 million years old.4 Outcrops of the fossil insect bed occur for almost two miles (3.2km) along a ridge. Its lateral extent has never been traced due to housing estates and industrial developments in the surrounding areas, but it is believed to extend at least six miles (9.6km) in a one mile (1.6km) wide belt in a general northwest-southeast direction.
The fine grain size of the tuffaceous chert bed has facilitated the detailed preservation of even the venation in the prolific insect wings entombed therein. Stratification is pronounced and well-defined joints cause the tuffaceous chert to break into rhomb-shaped blocks. In some cases the fresh, grey to black rock is so highly silicified as to be slightly translucent, and all evidence of banding is obliterated. This insect bed is underlain by a 15-18 ft. (4.6-5.5m) thick sandstone, beneath which is a very prominent bed of coarse, strongly-cemented conglomerate consisting of water-worn pebbles (including pebbles of coal). Fossil wood is abundant in this underlying sandstone, including sections of fossilized tree trunks up to 18 in. (0.46m) in diameter.
Fossil insect remains—predominantly wings, but including portions of bodies—were first recognized in this tuffaceous chert in 1898, and subsequently nearly 2000 specimens were collected and registered at The Australian Museum in Sydney.5 It has been estimated, extrapolating from an average yield of 10-20 fossil insect wings per cubic foot, that there could be some hundreds of millions of fossil insect wings per square mile preserved in this bed.
Had a college geology professor that found Trilobites on Engineers Pass near Ouray, CO at 13,000 plus feet.
Trilobites, extinct marine arthropods, form one of the earliest known groups of arthropods. Geology records are amazing.

I won a Science Fair for reproducing the environment of a pair of Egyptian Spiny Mice in a 20 gallon long tank and my award was a fossilized fish on a white chalky like rock. I was awed that I was given such a treasure.
I did this arrow head this arvo. This is the best flaked one so far, because I started with a much larger piece to make a decent bi-face, instead of 'cheating' by using thinner flatter flakes, which didn't need as much work to shape. You can see the choncoidal flakes especially on the left side, going across the bi-face to meet up with a nice centre flake I manage to get to break off, going from the rear to the point. I will contiue to notch it, to finish it off. ____ sent me some roo tail sinew, which I will use for a few of these points, so stay tuned.
E, You definitely have me wanting to go out and to start collecting rocks again. I'm going to gather as many different types as I can and I'm going to document them for my own records. I find that if I draw what I see, I develop a photographic memory for it that's pretty permanent. Thanks for taking the time to contribute your work here mate. I have a lot of catching up to do with you.

Obsidian is beautiful. I wish we had it here. Nice work Bear, do you have any more stuff you have knapped? I notice knapping is more known and also practised in the states, you have some fantastic knappers a and also great knapping material suppliers.
Aboriginals here, never discovered or used the bow and arrow for some reason? I think it would be great to find randomly knapped native arrow heads from long ago, like you guys can.
This is one of 7 that I have made for both wearing and I can use in the woods if necessary.
I wear it on a daily basis. It is laced with a piece of waxed jute that makes it easy to take off an bind to an arrow shaft, which I can use to kill game. . . .or the ever present Homosapienus Zombius Flesheaterus Killerus?!
