Digging In Gravel And Rock.... How Do Ya'll Do It

[Deep1]

Got access to an old very early drive in, you know, with car hops and curb service.
The lot as I remember it, was dirt.
Well, under the dirt is rock of different sizes, in some areas it is small gravel 1/4 to 1/2, in another it is big rock from an inch to maybe 3 inches.
It been driven on and packed for over 70 years.
It is all bound by a very hard, fine black dirt. It's so fine it disappears, whenever I refill the hole all there is a pile rocks.
Never tried to dig in ground like this and it's kickin my butt.
There's coins everywhere. Every few steps is a target.
In 2 or 3 hours I might recover 8 or 10 targets and I'm only diggin 3 to 6 inches. After that I'm wore out.
I've tried Leshe shovel(don't work too good), hand tool(worked better) and a 5/16 probe with a flattened tip( worked ok).
My next thought is a small pick ax.
The problem is I cannot make big holes, otherwise I would have a mini excavator with me.
Is it easier to dig when it's wet? We've had no rain for a while and the ground is very hard.
I could take a water tank and wet the ground.
Any suggestions from the rocky ground diggers?

It’s rough, have you tried twisting the shovel? Sometimes catching the edge of a rock and twisting works better than trying to pry upwards

Good place to hunt, but you are going to work for every target!

A pick ax may be OK if you are careful...Wet ground would be nice if it rains for you. Good Luck on your adventure!

Try the scraper method like ol Two Toes uses...

it should be alot easier after a good rain...

my predator ranger shovel does a good job in stuff like that...

screw driver and hammer. No Im not joking. Use those knee pads that painters/ roofers wear. Also a thin stone masons chisel or cold chisel work well. Did a carpark at my mother in laws shop. Was a truck stop for 30 years so some interesting finds. Sounds like the same kind of situation

been there done that and your right it's tough diggin , chub has the right idea and don't forget they ran speaker wires underground....have fun...

Nice tip, Chub. I have spent too long digging in packed gravel for targets. I already carry a sturdy screw driver. I'll put a hammer in the truck!

Depending on how worried about damaging your finds I would think an auger would do the trick... like small motor on a tripod style.

Like the screwdriver, hammer idea.
It rained today, got about a 1/4 inch.
Wow, what a difference.
I can kinda get my digger in the ground a make a hole.
It cut my time from 5 minutes an inch to 1 minute.
Still pretty tough diggin.
Where there was a little water standing, diggin was easier.
Gonna take a 100 gallon water tank, flag my targets and soak em down.
Thanks for the input.

I have used my commercial cordless hammer drill on packed gravel from time to time just to loosen the gravel. It works swell. You can buy a non-commercial grade cordless hammer drill fairly inexpensively. Although I have never used a non-commercial one, I would think the concept would be the same.

Are you finding silver? If it isn't silver, I'd find somewhere else to dig. IMHO.

I like hammer drill better than auger, do you use an actual bit or a spike or a paddle?

I just use a 1/2 inch masonry bit and sorta slowly wallow it around the hole.

Terrys got the idea! Way back I used an Estwing rockhammer. Pinpoint and loosen the gravel around it. Worked excellent at a drive in covered in pea gravel.
