Île de la Réunion, off Madagascar.....mid/late 1980s.
We had taken a helicopter ride over the (then dormant) volcano, so decided to drive up.....approaching the sight we noticed that the rocks alongside the dirt road entrance were all whitewashed, and wondered why.
Parked the car, walked down about 80 steps on the staircase.....at the bottom big sign, en Francais, warning about sudden temperature drops/fog.
Ah, it was a hot sunny day and we didn't have far to go, so let's...
Encountered a group of returning hikers, rugged up for a trip to Baffin Island in January - they stared at us, we stared at them.
Then....the fog....whoops......it came in fast & cold.
Could barely find the stairs or the car...on the way out we acknowledged why the rocks were white.
