CORE works with Volunteers for Outdoor Colorado on the South Park Trail Restoration at Guanella Pass

 CORE Team @ South Park Trail

CORE Team @ South Park Trail

On August 18-19, 2018, thirteen members of the CORE family spent their weekend working on a trail restoration project at South Park Trail located off Guanella Pass. The restoration included repairing a perennially wet area of the trail that was in a state of disrepair due to erosion and foot and horse traffic. The CORE team, along with several other volunteers, worked together to build an elevated trail surface known as a turnpike to prevent the area from becoming permanently saturated.

The South Park Trail restoration project was a not only a way to give back to the community, but an extraordinary team building opportunity that brought CORE employees together. In addition to the trail maintenance, the CORE team enjoyed camping, meals, drinks, and corn hole over the two-day event.

CORE is passionate about giving back to the community and encourages employees to volunteer with organizations that have meaning to them. All CORE employees receive two paid volunteer days annually.
