If you could move Alaska south and place it over the contiguous United States in such a way that all its land would fit, it would not only go from Minnesota down to Texas, it would stretch all the way from Florida across to California. Here is how it could look:


Now let's see how this works out in numbers: obviously, the exact distances depend on how we fit the Alaska map over the "lower-48" map. At its maximum Alaska is 2,261 miles (3,639 km) wide and stretches from Longitude 130°W to 172°E; as the crow flies it is 2179 miles (3509 km) from Attu Station, AK to Ketchikan, AK. To fit the Alaska map on the lower-48 we need an as-the-crow-flies distance from somewhere on the California coast to Florida:

San Diego CA to Jacksonville FL is 2,092 miles (3,347 km)

San Francisco CA to Jacksonville FL is 2,372 miles (3817 km)

So, yes the Alaska map stretches across the whole of the coast-to-coast map of the lower-48.
