Mercury's surface in "enhanced color," a color scheme created to emphasize color differences. This is not what Mercury would look like to the human eye, but by applying mathematical analysis to images, color differences can be accentuated beyond those visible to a person.
Mount Rushmore National Memorial under construction.
The workers had to endure conditions that varied from blazing hot to bitterly cold and windy. Each day they climbed 700 stairs to the top of the mountain to punch-in on the time clock. Then 3/8 inch thick steel cables lowered them over the front of the 500-foot face of the mountain in a "bosun chair." Despite the dangers, no one was killed during the project.
Otters in Glacier Bay National Park and Preserve, Alaska.

The U.S. Department of the Interior´s International Technical Assistance Program (DOI‐ITAP) builds capacity in other countries by drawing from the diverse expertise of DOI employees. Capacity building includes on‐site technical assistance, U.S.-based training, one-on-one mentoring, and train the‐ trainer workshops. DOI typically contributes the salaries and benefits of its technical experts while external funds cover other expenses (e.g., travel costs). Working with the U.S. Agency for International Development (USAID), the State Department and other funding partners, DOI-ITAP activities span the globe, having worked in more than 60 countries.
DOI specialists have a depth of applied technical expertise, domestic and international experience, and relevant language skills, on which DOI‐ITAP relies to field interdisciplinary teams from multiple bureaus. DOI-ITAP managers guide and work with these specialized teams, as well as in‐country coordinators, to foster direct and sustained government‐to‐government professional exchanges with their counterparts in other countries. DOI‐ITAP partners with local and international NGOs as well as private contractors, lending unique government‐to‐government expertise to technical assistance projects while leveraging resources.
DOI‐ITAP offers technical assistance on all areas of DOI technical expertise, including:
