A big thanks to the AAPG Foundation for their support for our work on Rockd this year – we hope to continue this partnership into 2026

Macrostrat stratigraphic column viewer

Happy 2026 from Rockd! For the new year, we released version 4.1, which improves the checkin feed and brings our stratigraphic column viewer out of beta!

This update and #AAPG Foundation support position us for many great features to come.

As always, please let us know what you think!

We've also fixed a raft of other bugs, including a supremely annoying one where the location of the map periodically reset to your location. Now it's easier to explore!

Fun historical fact: most of the @macrostrat.org stratigraphic data for North America is derived from the COSUNA stratigraphic chart series.

Putting this seminal compilation a tap away from any geologist anywhere is a fitting way for #AAPG to honor the 40th anniversary of its creation!

The biggest new addition is a stratigraphic column display, found in the "stratigraphic unit" tile on the Dashboard and map info panel.

This is still very "beta", but it's nice to finally interact with the time dimension of the rock record, which has been core to @macrostrat.org from its beginning.

Excited to inaugurate this feed to announce the release of Rockd Version 4, our first "major version" update since 2022! This renewed phase of app development was supported by the #AAPG Foundation.

It's mostly internal fixes for now, but there are some fun new features for geological exploration...
