Lizard Contributors 

Purple Lizard Cartographic Contributors include a small group of some of the best cartographers, designers, and adventurers anywhere - who all share our passion for exploring the outdoors.

Lizard Contributors do lots of cool things in the world, and also work with us with us on special assignments to help bring Purple Lizard's Maps to life. Below are a few of our key contributors.

Erin Greb of Erin Greb Cartography has always had a close connection to the outdoors and exploring. Growing up with acres of woods in her backyard in western Maryland and driving cross-country every year with her family on vacations, maps always played an important part in her life.

Erin Greb Cartographer

As a second year art major who loved to hike in the mountains near Penn State, the lightbulb went off one day that she should transfer into Geography (’99) and learn to make maps like the ones she used in the woods (including the original Rothrock Purple Lizard map!). Erin then earned her MA in Geography at CU Boulder (’02) where she continued to hike and mountain bike in the foothills and Rocky Mountains. Now she continues to explore and design maps and enjoys traveling around the country for trail races. 



Wiggus came to this planet to save mankind, but after living here for 20 years he decided to play guitar, ride motorcycles, and pursue his lifelong dreams of mastering the art of digital design and working with Purple Lizard Maps.

In Memorial: Karma the Adventure Dog (2012-2023)

Karma the Adventure Dog is in the spirit of Purple Lizard Maps and always will be.  For 13 years during the making of many many of our maps, Karma went everywhere Purple Lizard, was responsible for investigating anything worth investigating, making friends with anyone and everyone he met, and most importantly maintaining a fun and peaceful atmosphere for all who knew him.  Karma left us suddenly and unexpectedly from cancer in the summer of 2023, and we will miss his company and pure and total joy being outdoors - his adventurous spirit is and always will be a part of every map we make. May you always run in peace Mr. K!
