Overview ACES' Commitment to Education The Aspen Center for Environmental Studies at Hallam Lake has served students and teachers of the Roaring Fork Valley since 1975. ACES' education goal is to promote understanding of natural systems and cycles, emphasizing the importance of all life, the need for diversity, and our integral position as a part of all earth’s life. Further emphasis is placed on developing a sense of responsibility for the earth as a complex and finite natural system. Currently, ACES' experienced education staff makes nearly 30,000 student contacts annually and provides over 330 field trips each school year to pre-school through high school students.
