Please note:

  • Two details on Merritt’s posted class schedule are wrong. 1: Students do not enroll in all trips; each student signs up for ONE trip. 2: Trips are not cancelled due to weather conditions, but a posted destination may change depending on weather, road conditions, or phenology.
  • Costs: Trip fee $20 (includes shared equipment such as water filters and stove fuel). Additional expenses include carpooling (riders cover all fuel costs for drivers) and may include campground fees and wilderness permit fees where applicable. Participants carpool for all trips; class meets by arrangement at the destination.
  • Students who have enrolled in the class and emailed their trip requests will be signed up for their first choice trip until the trip limit is reached. Each trip is limited to 12 students, except for Trip 4 which is limited to 8 students. Students who request to sign up for a trip that is full will be notified that they need to select an alternate trip.
  • Each participant should be in good shape and be able to hike/backpack/take care of personal needs/keep up with the group AND have enough energy remaining to learn about plants while exploring the outdoor environment.
  • Each participant provides their own food and personal camping equipment.
  • REI offers classes in basic backpacking skills. This is a botany class.
