Participants will be able to participate in surveys at sunrise, sunset, or both. Camping will be provided. Camping may be available closer to the Silvies Floodplain. Camping gear is available for participants to use during this event. Most routes will travel along gravel or paved roads. Some routes may require short hikes.
