Can anyone identify this weed? It is a huge mound and I'm in Zone 6. I thought maybe wild parsnip or something like that. Thanks!
It would help us if you could post an image of the entire plant.
It could be Pastinaca sativa, wild parsnip. If so the sap should be avoided, it can react with sunlight and cause blistering.
