JARVIS REC: Central Valley Junction (Foxdale-St John's)

TERRAIN ANALYSIS: Where the Foxdale mining valley meets the St John's agricultural plain — a natural convergence point. Tynwald Hill sits at this junction. WHY: (1) Tynwald's location wasn't random — it was chosen as the GEOGRAPHIC CROSSROADS of the island, (2) Mining traffic from Foxdale passed through here, (3) Agricultural markets at St John's, (4) The main east-west and north-south routes cross here. This is IoM's CENTRAL HUB — the most-trafficked inland location for millennia. Strategy: detect fields around St John's village, along the old Foxdale road, and especially anywhere old tracks converge.
