For the last 15 years, Margot Cowan has volunteered her time to the Arizona Migrant Trail, an organization focused on bringing border issues to light.
She will be walking alongside dozens of other people from Sasabe, Sonora to Tucson, Arizona to remember all the people who have died while trying to cross into the United States.
"I walk for more just border policy, I walk in memory of the thousands of people who have died in our desert, I walk for their families, their mothers and fathers, their children, their parents."
According to the US Border Patrol, since 1998 there have been more than 7,000 deaths along the Southwest Border region.
In 2016 in Tucson, 84 people died, compared to last year when 72 people died trying to cross the border.
"I think that it's important that we create a just border policy. People shouldn't have to die to come to the United States."
The dozens of walkers will follow the highway on their journey. They are expected to arrive in Tucson June, 3 at Kennedy Park for a closing ceremony.
