> the more you associate memories with navigable places, the stronger your memories will remain.

Some of us have a location synaesthesia where thinking about particular topics often evokes a sense of being specific places, looking particular directions, each paired apparently randomly (but durably) with topics. Not sure if this is association (since it seems to form without any associating event with the location) or just signal "leakage" triggering the connection.
