To find the main Chengwatana gravel pit / "shooting range" do the following:
Open Google Maps
Google "Hustletown Union Cemetery"
It is located on Forest Rd (also called County Rd 10 ) East of Pine City MN.
Follow Forest Rd East 2 miles where it makes a gentle curve to the North and becomes Evergreen Rd.
Off the center of that curve, take the gravel road about 200 ft South to the gravel road going due East.
There is a large wooden sign there for Chengwatana State Forest.
Continue East on that gravel road into the forest land.
You will drive past the silos of the farm on the corner and his fields.
The gate for the forest is about a mile in.
This gate is closed in the spring until the road conditions are good.
You will pass some small pull off / parking areas where people also do some shooting.
You will also pass a large pond on the North side of the road.
Don't wander off the road while gawking around. You will be stuck!
Continue East until you come to the only Y in the road.
Take a Right to the range.
(A left goes to a parking area for ATVs, snowmobiles, dirt bike trails)
The "range" shows up as a large white area East of the road, just after the road crosses Red Horse Creek and turns South.
(use Google maps, satellite view, 1000 ft scale)
The gravel road dead ends at a turn around / gate about 1/4 mile South of the range location.
This "range" is maybe 100 yds, depending where you set up to shoot from.
Someone recently (this summer) built two very nice wooden benches to shoot from.
Rock solid and extremely well built, anchored to 6X6 posts in the ground.
If you switch to satellite view, and zoom into the 50 foot scale, you can see a couple of logging trucks at this site on the current Google sat view image.
The logging is over and done.
A cable on posts has been strung up to separate the parking area from the sand/gravel pit.
There are also huge rocks placed to keep vehicles out of the pit.
There is a small berm / bank to the back (east) of the range.
Be aware: ATV's can and do go on the trails far to the East in the woods.
There is a small camping area about 100 yds South of the range.
The current sat view image shows a large white trailer there.
Have fun, but do so responsibly.
Please have the decency to clean up after yourself.
Don't blast glass and leave it!
Take your shot up cans and other garbage with you when you leave.
Leave it cleaner than when you arrived and we will all benefit

Just maybe this will be here for our grand kids to enjoy.
