CREATE TABLE table_10259 ("Rank" FLOAT, "Mountain Pass" TEXT, "State" TEXT, "Elevation" TEXT, "Route" FLOAT)

What is the route that has a rank higher than 63, and Separation Summit as its mountain pass?
SELECT SUM("Route") FROM table_10259 WHERE "Rank" > '63' AND "Mountain Pass" = 'separation summit'
SELECT SUM("Route") FROM "table_10259" WHERE "Mountain Pass" = 'separation summit' AND "Rank" > '63'
