Fly to Ontario, pickup rv, drive 1.5 hrs to Hammertown, stay there.
Flight is usually around $400,
RV is around $1000, including gas, water refill on lakebed,
Food is available on lakebed but is pricey.
Figure on 5200 mile round trip if driving, so $1500-$2000 on fuel. Less if towing sxs. More if stopping at hotel each night/fancy restaurants.
The catch is transportation around on lakebed. Need something to get from a-b to see some of it. 4wd truck or suv rental is $600-$1000.
It’s much easier to work out as a group. Some flying, some towing. Cost splitting etc.
Can spend more or less but that’s middle of the road.
or you can volunteer to work with a team and you will be surprised how much fun it is and how much you get to see first hand.
