As a member of Ashley's expedition, Clyman wrote one of the two accounts detailing Hugh Glass's mauling by grizzly bear.
[1] Clyman also traveled with Jedediah Smith, whose scalp and ear he sewed back on following a savage grizzly bear mauling, and Thomas Fitzpatrick in the discovery of the South Pass.
[3] He spent some time in Milwaukee County and made the decision to venture further north in the fall with his friend Ellsworth Burnett.
[4] They left on November 4, 1835 and on the second day out, they were attacked by two Native American men near present-day Theresa, Dodge County.
[3] This story became well known in the region and when in the years afterwards immigrants started to settle Dodge County they named one of the towns "Clyman" to remember what once happened in the area.
In later years, he traveled back West, crossing the Great Salt Lake Desert and the Sierra Nevada.
