Narrative:

We were cleared to taxi to runway 31; intersection F for departure. As we approached taxiway F I noticed the taxiway; which runs perpendicular to the parallel taxiway referencing the runway; had a pronounced crown. I was distraction by having to taxi over this crown without causing damage to the aircraft and did not see the hold short line; which I believe may have been on top of the crown on taxiway F. As we approached the end of runway 31 the tower notified us we had crossed the hold short line. In a phone call with the tower supervisor; he said he wanted me to be aware the 'new' hold short line was located 1200 ft from the runway 31 threshold. I believe this incursion could be averted in the future by not having the hold short line co-located with the crown on taxiway F.
