This a quote according to paulmirocha:

"Because of the nature of Tumamoc as an ecological research preserve with over 100 years of continuous long-term study areas, and the huge recent increase of visitors, all trails on Tumamoc Hill including the trail from A-mountain park are now closed. For the same reasons, hikers are asked to become stewards of this valuable urban wilderness and stay on the paved road. This road is off limits weekdays 7:30 to 5:30 due to traffic going to the Desert Lab and towers on the summit. Evenings, mornings and weekends are good times to go. The summit is a sensitive archeological site that is also closed to the public except by permission, due to increasing vandalism"

It appears that Tumamoc Hill is now closed off to hiking during the weekday. I will be looking more into this very soon. Thanks paulmirocha for updating me on Tumamoc Hill.
