Staff at Mesilla Valley Bosque State Park will host a Nature Trek titled "Winter Adaptations" at 10 a.m. Friday.

Join park staff and discover how animals and plants in the bosque respond to the colder temperatures. Where do the frogs go? What happens to all of the insects? How do amphibians and reptiles stay warm? Explore the bosque and find out the answers to these questions. Both adults and children are welcome.

Entrance fee is $5 per car or annual day-use passes are available for $40.
