“Corona” Course at Trione-Annadel State Park

Dates: June 27, 2020 to ??
Location: Santa Rosa, CA
Course Setter: Gavin Wyatt-Mair
Type: Training; Streamered Middle course for practice/exercise during the shutdown


General Notes:


I have streamered an interesting Middle training course at Trione-Annadel State Park (https://www.parks.ca.gov/?page_id=480). (We’ve known this park as Annadel State Park, but California State Parks renamed it Trione-Annadel State Park in 2016 to honor the primary benefactor of the park.)

A Google Sheet for registration is here (https://docs.google.com/spreadsheets/d/156Ld2Hx7iy7F9CgcHr9cs5GrpZanDzr_WA2bU468P38/edit#gid=0). Please use it to enter your expected start time, as well as your time on the course. (We want to know that you returned safely!)

This is just for fun, so everything is on the honor system: time yourself if you wish, “punch” at each control by getting within 1 meter of it (like an air punch; no need to touch anything).

Course Notes

Annadel is a wonderfully complex park. The course technical difficulty is high, and typical for a Middle course; you will need to be very careful with your fine navigation. Running conditions are good, there are lots of rocks, there are stickers, but not much poison oak (which you can avoid).

The course statistics are:

Annadel “Corona” Middle: 3.9 km, 140 m climb, 16 controls

The controls themselves feature pink streamers, usually wrapped around a tree trunk or hanging on a branch, about 2 feet from the ground.

Safety

Map

The course map is available here (1.3MB PDF). Please print your own map. It fits on letter-sized paper (8.5x11, Portrait orientation).

The map is old. Bill Cusworth vetted the course and made some important map corrections (Thanks Bill!). This map is not Lidar-based; the vegetation has changed a bit; the rocks have not moved.

The map scale is 1:7500, with a 5-meter contour interval.

Note: A new version of the map was posted at 9:30 AM on July 7 (the new file name includes "v2"). (For reference, the original map is available here [1.3MB PDF], but please do not use that map to run the course.) Gavin explained the changes as follows:

"We moved #11 east a bit to avoid the temptation to cross the meadow, and also made some small improvements to the map quality in the vicinity of various controls.
"The course was 3.848 km long, and is now 3.859 km long. Condes rounds down, so the old clue sheet says 3.8 km and the new v2 clue sheet says 3.9 km, but actually there’s only 11 m difference."

Directions and Parking

Park on Park Trail Drive near these coordinates: 38.440809,-122.653128.

Note: That location is on the west side of the park, far from the main park entrance.

From the street-side parking on Park Trail Drive, it is about a 1.2 km walk to the Start and 2.5 km walk back from the Finish.

The map has arrows and an inset on it to help you get to the Start and to get back from the Finish. [Editor's note: If the inset is not displayed when you open the map, close it and open it again. (It happens to me. 🙁)]

Here are written directions:

Miscellaneous

Dogs are not allowed in the park.

If you’d like to donate to the club for this, please do so at a future event ... whenever that will be.

Again, you don’t need to touch anything, and you don’t need to get anywhere near anyone else. Of course, you are on your own recognizance, at your own risk.

Have fun!

Cheers,

Course Comments

I really enjoyed doing the Annadel course today. How long has it been since we have been allowed to hold a regular event there? 10 years or more? Too bad, since the terrain is first-rate. Perhaps we should continue to set streamered practice courses on maps that we can no longer use for regular club events, even after the current crisis is over. China Camp also comes to mind as an area at which I would like to go out on a practice course, by myself.

[Editor's note: The latest event at Annadel was in Nov. 2012. That event followed an even longer gap from March 2003 (http://baoc.org/results/r03/r030330.html) (which had 413 participants, with 300 on the White & Yellow courses!).]

I had forgotten how rocky the terrain is in that part of the map. Rocks everywhere, and it was sometimes difficult for me to figure out which rocks were on the map, and which rocks were not. So I made a few navigational errors, and a couple of other times, I did not see the pink streamer right away, even when I was almost right on top of the control location. In any case, it was a really good map-reading and compass-work exercise, of the type that we don’t get on most of our other maps.

The only streamer that I could not find at all was at #8. It’s hard for me to believe I was at the wrong fight patch, as there was only one in the area, and I took another bearing back to it from the trail junction SE of the control, just to make sure. So I hung another pink streamer there, although, given my track record in finding streamers, it’s entirely possible that the original one was there all along. I also hung a small streamer at the start triangle, as it wasn’t at a completely obvious location like a trail junction. (But oops, I’m noticing just now that the control description of the start triangle is on the west side of the west rock, not between the two rocks. I hung my streamer between the two rocks. Maybe the next person who goes out there can adjust it ....)

The walk to the Start was a bit of an uphill slog, but the walk back to the parking area was mostly down a very pretty shaded canyon, which I certainly have never been to before. So don’t let the long return walk dissuade you from doing the course.

Thanks to Gavin and Bill for setting this up!
