@aesiege @imarshad and all Pak wheelers
Following is the map which was distributed by the Pak Army for facilitation of the festival visitors, and became a reference map for our expedition. If you look closely at it, it shows the Kalam-Utror section in red color, which is marked as a Main Road in the legend / map key. Some section onwards from Utror is shown in black color, which is marked as a Jeep-able road in the map key. The next section upto Jandhri is shown as dotted red, (which infact does not fall on the Utror - Thal track) which is marked as a Hiking / Walking track in the map key. Another thing to note is that Jhaz Banda is shown right on this dotted red track and another dotted red track to Jhaz Dand shoots-off from Jhaz Banda. The track from Jhandri to Thal is in black color showiing it as a Jeep-able track. My conclusion is that this map is obviously a not-to-scale map and thus not fit for use by trekkers / hikers or even travelers who intend to cover the Utror-Dir track. My confusion now stands removed and I thank all those who helped me clarify this point.
