I think you are right, have just looked in ULSA Explorations 2 and there is an OS map with Penyghent, LHP and Hunt Pot overlain on it so I presume some digital form of the survey data must exist. I will email AT and Monico to ask if they know more.
I am interested in further prospecting across this area as it seems to me that the area has been unduly neglected by non-diving dales cavers, and with more effort could yield some amazing cave systems. ULSA, as you may know, has a project to survey the Fountains Fell caves to grade 5 standard. This will be a good platform for finding more caves in this area, but surveying gets boring after a while and new entrances would be excellent. Don't worry: I don't plan on doing any digging here any time soon, certainly not without speaking to the landowners and Andrew Hinde. But it seems to me that it is something worth attempting to kickstart a bit.
I also want to branch out with my GIS skills and this area would be an interesting one to begin with.
