Congratulations, definitely some shock-breaking, tire-popping and gear
straining territory. There are some trails on the South side of Jumbo Peak
that will take you to some springs with many signs of early man, including
some stone hunting blinds and lithic scatter. I am not sure if this area is
federal or not but I would not touch any artifacts just in case.

34 pounds might qualify for a new chondrite record here in Nevada!

Happy Hunting,

Adam
