MOOSE, Wyo. (AP) - Grand Teton National Park and a national park in Argentina are exchanging trail crews and other park employees under a sister park agreement.

Grand Teton has been a sister park with Los Glaciares national park since last year. Both parks contain rugged granite peaks and glacially carved valleys and have a history of ranching.

Several Grand Teton employees traveled to Los Glaciares to share their professional expertise last year. This past August and September, employees from Los Glaciares visited Grand Teton to expand their knowledge of trail maintenance and park management.

This winter, Grand Teton's trail supervisor and other staff plan to make another trip to Los Glaciares. Grand Teton Superintendent Mary Gibson Scott says the partnership offers a valuable learning opportunity for her staff.
