One of the most faithful landmarks known to man, which national park is home to this geyser?

Old Faithful was named thus due to its fairly predictable eruptions. Although you probably shouldn't set your watch by the geyser, you can fairly guess that it will erupt regularly, based on its past frequency. Located in Yellowstone, America's first national park (and the world's!), Old Faithful was happened upon by the Washburn Expedition in 1870. Erupting to a height of around 130 to 140 feet on average, the 1.5 to 5 minute-eruption occurs about 20 times a day – so around every 74 minutes, give or take.
