Firefighter watching the Boundary Fire
Firefighter watching the Boundary Fire

The Boundary Fire was a 2017 wildfire in Arizona that burned 17,788 acres (7,199 ha) of the Coconino and Kaibab National Forests. The fire was ignited on June 1 when lightning struck a spot on the northeast side of Kendrick Peak within the Coconino National Forest. The fire spread rapidly because of high temperatures, steep terrain, leftovers from a wildfire in 2000, and high wind speeds. The winds blew smoke over local communities and infrastructure, leading to the closure of U.S. Route 180 from June 8 to June 21. Smoke was also visible from the Grand Canyon. The Boundary Fire burned out on July 3, 2017, after 32 days of firefighting. The cost of managing the fire was $9.4 million (equivalent to $11.5 million in 2023). Damage to the area's foliage increased the risk of landslides into 2018. The Boundary Fire was one of 2,321 wildfires in Arizona in 2017 that burned a total of 429,564 acres (173,838 ha).

Today's featured picture


A peanut, also known as a groundnut, is the fruit of Arachis hypogaea, a plant in the family Fabaceae. The peanut is classed as a grain legume rather than as a botanical nut, although in culinary and colloquial use it is generally treated as one. Uses of peanuts include consumption as a snack and in various dishes, peanut butter, and – due to its high oil content – as a vegetable oil. Peanuts cause allergic reactions in some humans. Clockwise from top left, this photograph shows a peanut with its shell cracked open, a whole unshelled peanut, an unpeeled peanut seed, a halved peeled seed, and a whole peeled seed. This picture was focus-stacked from 31 separate images.
