Just north of the corner of 18th Street and Middle Road in Bettendorf is - strangely - a large head made of bark in an open field. More than 13 feet tall, it's hard to miss. What makes the sculpture feel truly immense, however, is how the artist has fulfilled her goal of "giving the Earth a voice" through this work.

The sculpture, created by Sarah Deppe - a 24-year-old artist from Maquoketa, Iowa - is meant to represent the natural world. Its surface is made of cottonwood bark found on the ground. As Deppe has written: "I incorporate bark and wood because I believe it is less detrimental for the environment than other mediums. I feel as though I am simply borrowing from nature, and it will be returned to the Earth as it decomposes off my sculptures."

The artwork's title, Exhaling Dissolution, refers to the pollution constantly being spewed into the environment.

Inspired by Deppe's research into deforestation, the artwork took four months to plan and construct. Since its completion in 2010, it has been displayed on the Northern Iowa University campus and along the Riverwalk in the Port of Dubuque before being installed in Bettendorf on June 29, 2012. The artwork will be displayed in Faye's Field for only one year - through June 2013.

On Campbell's Island is a war memorial side-by-side with an artwork dedicated to peace. One rises imposingly; the other is unassumingly low to the ground. Together, they give us a greater perspective on the area's history than if we were to consider them separately.

Campbell's Island is just north of East Moline, accessible from Illinois Route 84. The island is named for U.S. Lieutenant John Campbell, who was leading three gunboats past it on July 19, 1814, when his boat was grounded during a storm. While vulnerable, they were attacked by an estimated 500 Sauk warriors allied with the British Army. The attack led by Black Hawk and the ensuing fight became known as the Battle of Rock Island Rapids - one of the most western battles of the War of 1812. In all, there were between 35 and 37 casualities (depending on the source) among Campbell's men and their families - including the deaths of 14 men, a woman, and a child.

In 1908, the Campbell's Island State Memorial was dedicated on the site where the lieutenant's boat lay derelict for years. The monument is maintained by the Illinois Historic Preservation Agency as a state historic site.

The Charles J. Wright Transit Center at 300 West River Drive in downtown Davenport has two very different works of art related to travel. One is a sculpture of an impoverished Irish family traveling by foot. It is traditionally figurative and meant to draw you in emotionally. The other - modern and emotionally cool - evokes a sense of speed on a highway.

In the Heritage Court on the Palmer College of Chiropractic campus (at 1000 Brady Street in Davenport) are four large bronze busts. Sculptures of D.D. Palmer, his son B.J. Palmer, and his grandson David Palmer are placed symmetrically on a curved brick and stone wall with the incised words "The Foundation of Chiropractic." These men collectively presided over the Palmer College of Chiropractic for its first 81 years, beginning with its founding in 1897.

Slightly to the north is a bust of Mabel Heath Palmer, who is recognized as the "First Lady of Chiropractic" and was B.J.'s wife and David's mother.

Created by three different artists over a period of nearly 70 years, the sculptures are stylistically distinct. They are unified, however, by their consistency in height. Each bust is approximately five feet tall. Positioned on the two walls, they each reach a total height of about 12 feet. They also work together because of the consistent use of materials and conformity to a sculptural form from antiquity - the bust. During the Roman Empire, important families celebrated their achievements and honored their deceased relatives by displaying these sculpted portraits prominently and publicly.
