At the junction of Judge Branch and Spicewood trails are two signs, which are confusing and possibly inaccurate. You might assume the one that says "Judge Branch Trail, 1.7 miles" means you will reach that trail in 1.7 miles. Similarly, the other implies the Spicewood Trail is 2.5 miles ahead.
That's not how these signs work. They mark the beginning of those two trails, which split at this point. From here, the Judge Branch Trail continues for another 1.7 miles, and the Spicewood Trail is 2.5 miles long.
This kind of mile-marking is the opposite of how most signs are marked, including others in this park.
