Answer:
The correct answer is Easement by prescription.
Step-by-step explanation:
Easement by prescription is defined as an easement obtained by prescription by using the sirvient land in a particular, openly, exclusively, adversely and uninterrupted way for a determined amount of time. The user gets the easement with the years specified by state statute. So in Heather case she's been using the 22 acres that Pam owns to get to the fishing pond, in an openly, adversely, exclusively and uninterrupted way for over 20 years, therefore this is called getting an Easement by prescription.
