400 atmospheres
The atmoshperic pressure at 18,000 feet above sea level is 280 mm Hg.
The atmospheric pressure at sea level is typically around 760 mmHg. As you increase in altitude above sea level, the atmospheric pressure decreases. For example, at 5,000 feet above sea level, the atmospheric pressure may be around 625 mmHg.
300 feet of sea water exerts a pressure of approximately 130 psi.
Sea level pressure typically averages around 1013.25 millibars. Doubling this pressure would result in approximately 2026.50 millibars.
The pressure at 1200 feet below sea level is approximately 517.2 pounds per square inch (psi). This value is calculated using the formula: pressure = depth × density of seawater × acceleration due to gravity.
Buffalo, New York is 600 feet above sea level.

Murfreesboro, TN has an average elevation of around 600 feet above sea level.
it is about 600 meters in elevatiion (around 1968.5 feet)
At 14,000 feet underwater, the sea pressure is approximately 464 pounds per square inch (psi). This pressure increases by about 1 atm (14.7 psi) for every 33 feet of depth.
The atmoshperic pressure at 18,000 feet above sea level is 280 mm Hg.
Buffalo, NY has an elevation of approximately 600 feet above sea level.
600 feet if the mountain is already below sea level and so is the valley then just subtract the difference
