The starting view is from January, 1970, a field photo of Punta Ventana (“Window Point”) at Guayanilla, Puerto Rico (Monroe, 1980). The image fades to the March 5, 2020 color photo of the same location (ten Brink, 2020). The natural arch had collapsed from earthquake shaking on January 6, 2020 during the 2020 Southwest Puerto Rico Earthquake Sequence.

The Caribbean island of Puerto Rico, a territory of the United States, is only 100 miles long by 35 miles wide—about 2 ½ times as big as Rhode Island. Even though it is a U.S. territory, Puerto Rico has its own Olympic team. The largest islands in the U.S. Virgin Islands are St. Croix, St. Thomas, and St. John.
