Is Yakutsk Russia or Anchorage Alaska closer to the ocean
ivanzaharov [21]

-- The latitude at the northern end of the main runway at
Yakutsk Airport is 62.106° N.  That point is roughly 460 miles
from the closest point on the seacoast.

-- The latitude at the northern end of the main runway at
Anchorage International Airport is 61.199° N.  That point is
roughly 0.32 mile from the closest point on the seacoast.

Using these points of comparison, Yakutsk is 0.907° of latitude (62.7 miles)
more northerly than Anchorage, and Anchorage is roughly 460 miles closer
to the ocean than Yakutsk is.
