Context: Lumberman's Monument is a monument dedicated to the workers of the early logging industry in Michigan.  Standing at 14 feet, the bronze statue features a log surrounded by three figures: a timber cruiser holding a compass, a sawyer with his saw slung over his shoulder, and a river rat resting his peavey on the ground.  The granite base of the statue is engraved with a memorial that reads "Erected to perpetuate the memory of the pioneer lumbermen of Michigan through whose labors was made possible the development of the prairie states."  It is also inscribed with the names of the logging families who dedicated their time and efforts to the industry in the area.  It was built in 1931, dedicated in 1932 and is managed by the USDA Forest Service.  It is located in the northeastern part of the Lower Peninsula of Michigan along the Au Sable River within Huron-Manistee National Forests.  Access to the park is on River Road, which intersects M-65 west of Oscoda, Michigan.  Monument Road, from East Tawas, also leads directly to the monument, which is in Oscoda Township in Iosco County.  The monument is part of the River Road Scenic Byway, a 22 mi drive between Oscoda and South Branch that runs parallel with the beautiful Au Sable River.  It is a designated National Scenic Byway.

Nergis Mavalvala, PhD is a Pakistani-American astrophysicist known for her role in the first observation of gravitational waves.  She is the Curtis and Kathleen Marble Professor of Astrophysics at the Massachusetts Institute of Technology (MIT), where she is also the Associate Head of the Department of Physics.  She was awarded a MacArthur Fellowship in 2010.  Mavalvala is best known for her work on the detection of gravitational waves in the Laser Interferometer Gravitational-Wave Observatory (LIGO) project, but she has also obtained prominent results on other physics problems that evolved out of LIGO: for example, she has performed pioneering experiments on laser cooling of macroscopic objects and in the generation of squeezed quantum states of light.
