On this day in 1948, one full year to the day after the 1947 asteroid strike, the city of Roswell observed its first annual Rememberance Day. In the mid-1950s this holiday would be expanded to include several other towns in the vicinity of Roswell; by 1964 the New Mexico state legislature would designate it as a statewide holiday.

On this day in 1947, Roswell, New Mexico became the first American city to be hit by an asteroid. The impact left most of the town in ruins and killed nearly half its population in what would be later be called 'America's Tunguska'.
