Just had a little play around with this on my phone - am not a natural map reader (though have a friend who is) so my novice question is how do you zoom in on an orange spot if you are not sure what you are looking for. I know where most of the hillforts in my neck of the woods are (Wiltshire/Wessex) but am wondering if there are hillforts in the Yorkshire Dales as am going there in May for a walk about. Any pointers from anyone would be appreciated.
