The icon coordinates and waypoint 1 are one and the same, the start of trail at the kiosk. The first .3 mile section of trail is called the Oak Creek Canyon Whole Access Interpretive Trail and is a mostly shaded oak grove area that is accessible by all, including equestrians, bicycles, hikers, wheelchairs, disabled and blind individuals. There is actually a "guide cable" along the fence as well as informational signs in English & braille. The information you need to collect, to find the coordinates of the final, is located along this all access trail that ends at Waypoint 2 (approximately). The title of the sign or object you need to look at is provided, so you're not on a scavenger hunt for information. Note that the signs are not in the order you will see them, so pay attention. Read over the description, and then go find the information needed.
Calculate ABC and XYZ and subtract the values from the decimal minutes of Latitude and Longitude of the Parking coordinates respectively
ABC:
- ADOPTATRAIL SIGN: As you enter the trail, there is a kiosk on the right hand side with a green Adoptatrail sign, indicating the trail was adopted by the Hass Family - A is half of the size of the family (number) Adoptor has changed, A = 2
- WILD CUCUMBER: B is half the length of the dried out brittle spiny shell
- Walk to the end of the trail (where the fence/guide line ends) and walk through the "gate" and turn around. How many people do you see in the signs on the gate posts? Divide by 2, this is C
XYZ:
- REST AREA #1: X is one half the height (in feet) of the Black Sage referenced in the description.
- FALLEN OAK: sign - subtract the number of feet to your right the fallen live oak is, from the distance it is from the ground (just use the numbers). This is YZ
The checksum final coordinates is 48
The cache is a partially camo'd bison hidden out of sight. It's about a mile or so from the All Access Trail parking.

Happy Caching! A cache a day keeps the doctor away
Feedback is always appreciated on the difficulty/terrain ratings, cache descriptions, etc - thanks.
