Hmmm... Ed perhaps you need to dig a little further down than your well goes in case you hit oil, gold or diamonds!
What's your bedrock there? I'd assume from the term "white mountains" you were limestone, but 2 things make me fear that deduction... a) the white might be referring to snow and b) Them there mountains sounds too tall to be mades of chalk

Now let me think - was the old man of NH made of granite?
In which case you should have moor and tor topography (cool but it looks disheveled and is slightly radioactive) !
Your landscape doesn't look granitey at all so go on enlighten us!
