CMS Field Trip Rules

  • You can sign up online for a field trip. Reconfirm that you will be attending shortly before the trip date. This is good manners as well as good sense!  Trip leaders have the right to      refuse attendance for those not signed up and are not obligated to wait for unconfirmed participants.
  • Some trips are restricted with the number of people that can participate.  If you sign up and then cannot attend, please remove your name off the online sign-up page or notify the trip leader as soon as possible to release the spot being reserved for you.
  • On the day of the trip at the meeting location, the field trip leader will collect the Release and Waiver Liability Form for Field Trips that must be signed by all attendees.  Claim owners and landowners may have additional liability forms that need to be filled out and signed.
  • When you leave the field trip site, be sure to check with the trip leader so they know you and your group are accounted for.
  • You are responsible for the behavior and actions of your guests and minor children. Note that all guests and minor children must be members of CMS to attend club field trips unless we are conducting joint trips with other clubs.
  • At a few locations (for example old mine sites, operating quarries), safety issues or regulations may prevent minor children from attending the trip. Such restrictions will be noted in the trip write-ups.
  • If you dig holes looking for minerals or fossils, please fill it in the holes when you are done.  This is a requirements on all Federal Lands, as well as private lands.
  • Dogs or other pets are not allowed on any field trip.  Please do not leave your dogs in your vehicles during the field trip.
  • Respect private property of all kinds!  Do not disturb or remove claim markers.  Don’t trespass in areas adjacent to the field trip site. Ask permission if you must gain access to private land.

  • I will use no firearms or blasting material in collecting areas.
  • I will cause no willful damage to property of any kind such as fences, signs, buildings, etc.
  • I will leave all gates as found.

  • I will cooperate with field-trip leaders and those in designated authority in all collecting areas.
  • I will report to my club or federation officers, Bureau of Land Management or other authorities, any deposit of petrified wood or other materials on public lands which should be protected for the enjoyment of future generations for public educational and scientific purposes.
