The Jardine Juniper is an individual of the species Rocky Mountain juniper found within Logan Canyon in the Cache National Forest. Often credited with an age of over 3,000 years, core samples taken in the 1950s revealed that it was actually somewhere around 1,500 years old. It stands approximately 40 feet (12 m) tall and its circumference has been measured at 284 inches (720 cm). Discovered in 1923 by Maurice Blood Linford  while he was a student at Utah State Agricultural College (USAC), it was named after USAC alumnus and former U.S. Secretary of Agriculture William Marion Jardine (1879–1955).
