Antarctic Peninsula: Site Specific Crevasse Inventory Project

There are a number of well used sites on the Antarctic Peninsula with known ice-cracks and crevasses. There is some concern that as average temperatures increase on the Peninsula, cracks and crevasses may become more exposed and larger, or snow bridges over them may change and become weaker. The PTGA would like to continue to map these features quantitatively and qualitatively and seek information from any operators who have the skills and experience to safely collaborate in this important project.


To inventory known features at specific sites used by polar tourism groups for mass tourism activities such as hiking, sight-seeing and wild life watching.

This is a collaborative ‘guide sourcing’ project utilising information and resources from a range of guides across a range of companies. It is intended as an industry-wide resource for the benefit of anyone in the polar tourism industry.

The Polar Tourism Guides Association will be the repository for information and data and be responsible for keeping the inventory as current as possible and distributing it upon request.


  • To identify the main crack and crevasse features at specified sites.
  • To quantify these crevasse features in terms of: type, length (extent) , depth, width, depth to ground (if possible).

How to Participate

  • Photographs (particularly later in the season when the features are open and their extent is more visible. If you have someone with a drone this is the preferred option.
  • Safe GPS recordings (the more the better, at a number of spots along the feature.
  • Written description.

Send any images or information to the PTGA.

Known Features we are Researching

  1. Base Brown (Almirante Brown) bergshrund on the slope where many ships have excursions to the summit of the peak and some have snow sliding activities.
  2. Cuverville Island on the southern part of the snow cone and near the shore on the western point.
  3. Damoy Point where hiking takes place to the top of the hill.
  4. Danco Island ice cap at summit and south side.
  5. D’Hainau Island, around a small coastal depression under the snow earlier in the season near the southeast shoreline and where a small tidal lagoon becomes apparent later in the summer.
  6. Georges Point on the glacier adjacent to the penguin colony and southeast of it.
  7. Hovgaard Island especially the south ridge.
  8. Specific slopes above Mikkelsen Harbour.
  9. Neko Harbour on the slope above the penguin colony to the viewpoint.
  10. Orne Harbour bergschrund on the crest of the ridge of the western and eastern landings.
  11. Petermann Island on the ice-cap.
  12. Pleneau Island.
  13. Portal Point – numerous hazards beyond the first slope, including the narrow section and upper slopes very difficult to manage for mass tourism.
  14. Port Charcot along the higher slopes.
  15. Winter Island especially near Wordie House.
  16. Yankee Harbour on the glacier west of the penguin colony.
