A letterbox is another form of treasure hunting. Once a letterbox is found instead of signing a log book, you place your stamp mark in the letterbox's log book and place the letterbox's stamp into your own log book.

The Lions Club partnered with a Girl Scout seeking her Gold Award, in the planting of a Wye Oak seedling at Unglesbee Memorial Park in Libertytown, Maryland. She also planted a garden of wild flowers surrounding the tree and built a fence around the garden. The park was named for Charles Unglesbee who was a member of the club from 1954 to 1968 and was president in 1965. The Wye Oak was the largest white oak tree in the United States and the State Tree of Maryland from1941 until its demise in 2002 and was estimated to be nearly 500 years old. It measured 31 feet, 10 inches, in circumference, stood 96 feet tall, and had an average crown spread of 119 feet.

The Letterbox is hidden nearby in the park.

While you are there look for the Maryland Wye Oak Geocache. It is also located in the park.

Letterbox moved to a new location in the park on July 9, 2018 because of damage to original location.
