Kelly Martin and Katie Smart are part of a very small group of senior female firefighters around the world.
Kelly is the Chief of Fire and Aviation Management for Yosemite National Park in California, and Katie is only the third woman in New Zealand to become a station officer.
In 2016 Kelly testified before a Congressional inquiry into widespread sexual harassment, bullying and other misconduct at national parks across the United States, speaking about her own experiences including sexual harassment, that she had encountered in her three decades of service.
It's been a long and often lonely road for both women.
