Throughout history, sudden waves of opportunity—driven by economic surges, resource rushes, and bold speculative ventures—have fueled the rapid birth of “instant cities.” These settlements seemed to rise overnight, swelling with fortune-seekers chasing gold, oil, or new industries. Streets and saloons would bustle with activity, and fortunes were made in mere months. Yet, when resources dried up or economic winds shifted, prosperity vanished as quickly as it had arrived. What remained were ghost towns: haunting relics of ambition, now silent and abandoned. These vanished cities offer powerful reminders of how quickly boom can turn to bust, leaving behind echoes of dreams that once shaped entire regions.
