[roc-info] Orienteering this Sunday, October 24, at Rochester Rotary Sunshine Camp

[Richard Detwiler]

There will be a meet this Sunday, with a full range of courses: White, 
Yellow, Orange, Brown, Green, and Red. So there is something for everyone!

This is the last of the Club Series meets for 2010, which means the club 
champions in each age group will be decided.

Courses offered, along with the lengths, are given below. The climb is 
relatively insignificant, so I didn't bother to estimate it; even though 
there is a lot of sometimes intricate contour detail, there are no 
really significant hills to overcome.

    * White: 1.6 km, 9 controls
    * Yellow: 2.7 km, 11 controls
    * Orange: 4.2 km, 15 controls
    * Brown: 3.7 km, 12 controls
    * Green: 4.7 km, 14 controls
    * Red: 5.8 km, 15 controls (the Red course will be shown on two
      sheets, back to back in the map case, with roughly the first half
      of the controls on one sheet, and the second half on the other sheet)

You may start any time between noon and 2:00 p.m. All courses close, and 
controls will be picked up promptly, at 4:00 p.m.

Directions:

    *

      Take I-390 to the Rush exit (Rt. 251/Rt. 15)

    *

      Turn south (left, if you're coming from Rochester) on Rt. 15.

    *

      Go 2.75 miles south on Rt. 15, then turn left on Honeoye Falls
      Five Point Road (there will be a sign pointing to "Sunshine Camp"
      at the intersection).

    *

      Go about 1 mile on Honeoye Falls Five Point Road to the first
      intersection. Turn right, and go about 0.5 miles to the entrance
      to Rochester Rotary Sunshine Camp.

    *

      Park in the main lot at the Sunshine Camp.

    *

      The start/finish is in the Memorial building adjacent to the pond,
      which is about a 300 meter walk from the parking lot. There will
      be streamers and/or signs directing you to the Memorial building.

Important note: The bowhunting season for deer opened on October 16. 
Thus, there may be bowhunters on the DEC land! It is highly recommended 
that everyone on Orange, Brown, Green, and Red courses wear bright 
colors (blaze orange would be best). And please be courteous if you 
encounter any hunters. I'm sure we're not all that pleased that hunters 
will be in the woods, but they are also probably not that pleased that 
orienteers are running through the normally deserted woods! Keep in mind 
that both groups have the right to be there. There is very limited 
parking for the DEC land (two very small lots, each of which hold 2-3 
cars), so presumably if hunters are present at all, there should be few 
of them.

Adjacent to the DEC land and Sunshine Camp land is a gun club; it is 
likely that you will hear gunshots from the south. Don't be alarmed by 
that; their shooting is done in such a way that bullets do not stray 
from their property.

We will be using a brand new map, field checked in August through 
October of this year. The base map utilizes LIDAR contour data, 
high-quality aerial photos, and the previous map, made in 1997 by Karl 
Kolva.

The terrain will consist of the Sunshine Campus land, along with DEC 
land which borders the Sunshine Campus land on two sides. White and 
Yellow courses will remain on Sunshine Campus property, while other 
courses will utilize significant areas of the DEC land as well as the 
Sunshine Campus.

A few comments about the terrain and the mapping:

    *

      The scale is the fairly standard 1:10,000. The contour interval is
      2.5 meters, and there is extensive use of form lines to better
      show some of the more subtle land shapes.

    *

      There are a lot of rock features, probably more than any other
      local park.

          o

            Boulders are mapped as either a "boulder" (relatively small
            solid black circle), or "large boulder" (distinctly larger
            solid black circle).

          o

            The approximate cutoff for mapping a boulder is that
            anything knee high or above would be mapped. Sometimes
            boulders shorter than knee high would be mapped depending on
            their visibility -- if the boulder is large (long/wide) with
            a lot of rock plainly showing, it is generally mapped even
            if less than knee high at the tallest point. On the other
            hand, if a boulder is smaller and covered with moss (and
            thus not nearly as obvious in the forest), it would not
            generally be mapped unless knee high.

          o

            When boulders are higher than waist high (roughly 1 meter),
            they are mapped as large boulders. (Some are higher than
            head height!)

          o

            There is one cliff that is mapped.

          o

            Other rock features are boulder clusters (several boulders
            in close proximity, where it wouldn't be practical to map
            each one), boulder fields (a larger area of boulders, too
            many to map clearly), rock piles, and rocky ground.

    *

      There are quite a few rootstocks (root system of a fallen tree).
      The cutoff for mapping a rootstock is that it is mapped if 2
      meters tall or higher, at the highest point.

    *

      The Sunshine Camp and DEC boundaries are shown accurately on the
      map, and are fairly well posted, going either way, from Sunshine
      Camp to DEC and vice versa, and from Sunshine Camp or DEC land to
      private land and vice versa.

    *

      Many trails on the DEC land are indistinct in any season of the
      year, and are particularly indistinct in the fall, when they are
      covered with leaves. (They are shown as indistinct trails on the map.)
