69° on Nov. 14, 2016, the hottest reading for this week of the year since 1894. Next is 67° in 1939.
Marysville’s center stands about 20 ft above sea level. Within three miles the land runs from 0 ft to 500 ft, a difference of 500 ft: hilly country. Open water lies within three miles. The highest named summit within 15 miles is Blue Mountain, about 3,060 ft, 15 miles northeast.
Under the town center the state geologic map shows Younger glacial drift (fine-detrital, coarse-detrital), from the Pleistocene, less than 2.6 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 13×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Fine-detrital, coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 6 mi of the line.
Fine-detrital, coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 3 mi of the line.
Metasedimentary. Age: Devonian to Permian, 273 to 422 million years old. About 2 mi of the line.
Silt, sand. Age: Holocene, less than 12,000 years old. About 2 mi of the line.
Graywacke, argillite, siltstone. Age: Jurassic to Late Cretaceous, 66 to 202 million years old. About 1 mi of the line.
Sandstone, siltstone. Age: Middle Eocene to Early Miocene, 16 to 48 million years old. About 0.6 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Marysville reaches Puget Sound and the Pacific Ocean by way of Allen Creek and Quilceda Creek: about 6 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Marysville; river miles along the main stem, rounded.
Marysville has a warm-summer Mediterranean climate. Summer afternoons average 76° in August; winter nights fall to about 34° in February. About 40 inches of rain fall in a normal year.
On November 14 Marysville normally reaches 53° and falls to 38°. The record high is 69°, in 2016; the record low 11°, in 1955. The most rain on this date, 1.30 in, fell in 1966.
Normals 1991–2020 and records since 1894 at Everett, 5 miles south. NOAA, through RCC-ACIS.
