Salons & Competitions

Hidden Earth Survey Salon

Hidden Earth Survey Salon

The purpose of this salon and competition is to promote cave surveying and provide the opportunity for clubs or individuals to display their survey works. As well as displaying drawn surveys, other surveying-related material may be displayed as part of the salon and competition. This could include, for example, 3D models of caves.

How to Enter

Due to workload, online entry is not being used this year. Just turn up on the Saturday morning with your survey – don't forget to bring a label to display your name and the title of your work.

If you have any questions, please email:


For 2023 we are simplifying the categories, whilst we ease ourselves back into operation after four years away. All the survey entries will be judged alongside each other in a single competition. Also, there will be no delegate ballot this year.

  • Survey Salon – one winner 
  • Plus Distinctions and Merits

Competition Categories

For 2023 all entries will be judged in a single category.

The category is awarded a single first prize, and additionally, Merits or Distinctions may also be awarded in recognition of other surveying excellence.


  • Delivery of surveys
    Your work should be delivered to the exhibition area by midday on the first day of the conference. Postal entries are not accepted. If you are late in arriving you may find that there is limited display space left for you. You are expected to hang your work yourselves, under the supervision of the event staff. You should collect your work on the afternoon of the last day of the event. Work left behind cannot be returned.
  • Eligibility
    All maps, models or other physical representations of a surveyed cave produced in the 12 months prior to the event are eligible. Surveys that are (in the view of the judges), substantially similar to winning entries from previous Hidden Earth competitions or which (in the view of the judges) do not contain substantially new material will be disqualified.
  • Subject matter
    This can be any aspect of caving, cave science or mine exploration.
  • Entry limits
    Five entries per person, or per group/club.
  • Judging
    This will be by a panel of three judges whose decision is final. Note that the organisers reserve the right not to award a prize if, in the opinion of the judges, the entries are too few and of insufficient standard to constitute a competition.
  • Permissions
    All works entered for the competition must have permission from the copyright holder of the survey.
  • Display Requirements
    Printed surveys must be on paper or thin card. Frames are not permitted. Ensure your survey dimensions is appropriate to the category. Entrants to the ‘Other Displayed Material’ category are required to discuss their entry and any bespoke requirements (e.g. large amount of wall space) with the organisers in advance.
