The graphic above shows proximity to dedicated Latter-day Saint temples on thirteen dates from 1877 to 2006. For the first thirteen frames the colors indicate 150 nautical mile range bands: white, closer than 30 NM; green, between 30 and 150 NM; blue, between 150 and 300 NM; orange, between 300 and 450 NM; purple, between 450 and 600 NM; black, beyond 600 NM. The last five frames repeat dates from 1997 to 2006 with the colors indicating 50 nautical mile range bands: white, closer than 20 NM; green, between 20 and 50 NM; blue, between 50 and 100 NM; orange, between 100 and 150 NM; purple, between 150 and 200 NM; black, beyond 200 NM. Public domain data for coastlines and political boundaries were obtained from the USGS. The website LDSChurchTemples.com was a helpful resource for locating each temple.
