The Mazama ash is an example of a marker bed.
Explanation:
Marker beds are distinct strata that are found in other sites in the same region. They can give evidence to age of sediments in a new site if they’ve been assigned a date in other sites. The Mazama ash is consisted of fragments that were ejected into the air by a volcanic eruption of the Mount Mazama, from Oregon Cascades. It blew up 6900 years ago and the ashes were carried by the wind. When the ash settled, it created a marker bed.
