Picture42Along with the multiple stakeholder group of ADOT, Glen Canyon National Recreation Area, and the Navajo Nation, Lyndes worked with the multi-disciplinary team to design the natural resource restoration plan and the cultural resources interpretive plan. This project is located in the beautiful vermilion cliffs land of northern Arizona at the northern start of the Grand Canyon. The Interpretive Center design focused on local natural materials and draws from the cultural and natural context of the adjacent Navajo Nation, the historic Mormon exploration and the settlement and the adjacent Glen Canyon National Recreational Area.  Native American craft vendors were accommodated in the redesigned interpretive areas.

The project revegetation was guided by meeting the mission of the Glen Canyon National Recreation Area – that non-indigenous plant seeds would be prevented from dispersing into the Colorado River, which would create a problem of invasive species establishing along the river downstream. To address this, we designed a process and specification for special seed selection and harvesting from local canyons, contract growing of these plant materials, and plant harvesting and transplanting. We also designed a temporary irrigation system, gravity-fed – to serve the plant water needs during establishment. In the project visual assessment work we assessed the viewsheds, established parameters which focused the investment of money in the visually most high-profile areas and coordinated with the multiple stakeholder groups on acceptable treatments which preserve the unique quality of the site.
