Temperature, precipitation and snowfall figures are NOAA climate normals for 1991–2020 from station USC00273626, the nearest station with a complete set of temperature normals, 4.8 miles from the park. Conditions in the park can differ from the station's, most of all where the two sit at different elevations. Daylight is calculated for the park's latitude at the middle of each month. The acreage is what the USGS Protected Areas Database maps under the park's name. The state's own figure can differ, because the database may hold part of a park under another name.
