Event Overview

Come on out and tried the first ever CROC corn maze orienteering at the Pumpkin Patch on Sauvie Island! It’s probably the smallest scale map we’ve ever used, but DANG there’s a lot of route options! It's all the fun of a corn maze but with an extra competitive edge. Family and beginner friendly as always.

Number 1 rule: Stay only on existing paths in the maze and do NOT cut through standing corn.

Note - This event starts much earlier than our usual meets, so we can be finished with the course by the time the corn maze opens for business.)

Note - We expect a large turnout for this event. Please register online if possible, and arrive early to make the morning as smooth as possible for everyone.

Corn maze orienteering tips

  • You may want to bring a highlighter pen to mark your route on the map.

  • The map scale will be approximately 1:1500, a much larger scale (more “zoomed in”) than a normal orienteering map. Controls will accordingly be very close together, some just a few seconds apart, so don’t overrun your objective.

  • The orienteering skills of thumbing the map where you move your thumb along to indicate the “you are here” position), and orienting the map (by rotating it to match the terrain in front of you) will be very useful. Read about these two important skills in more detail on our “Beginner’s Guide” page.

  • Please bring: a watch and a change of clothes/shoes. Corn mazes can get muddy!
