Vetal Hill (tekdi) can be accessed from Panchwati Pashan, Senapati Bapat Road, or from Kothrud and has a number of quarries where few lava flows are exposed. We carried out field work in Panchwati and identified several lava flows in old (and now abandoned) quarries. Our field traverse started at the base of Panchwati hills and continued till the top of the hill where a large quarry is now being recharged and developed as a lake.
Stop 1: At our first stop on this field traverse we come across a quarry that we call Quarry 1. We see an outcrop approximately 25 feet high that extends approximately 100 feet laterally. Two separate flows are identified at this outcrop with a sharp contact between the two. While flow 1 appear massive and blocky, flow 2 appears more pillow like. Flow 2 is also more weathered.

Stop 2: At this stop, we encounter another quarry (Quarry 2) where the outcrop shows flows 1 and 2 seen at the previous outcrop.
Latitude 18˚31.998' N
Longitude 73˚48.790' E
Elevation 633 m
Stop 3: Walking further ahead we come across a vertical cliff face. The cliff is approximately 40 m thick and three separate flows (Flows 2, 3,and 4 and contacts between flows 2 and 3 and between flows 3 and 4) are visible. Flow 2 is approximately 15 m thick and flow 3 is approximately 10 m thick.

Longitude 73˚48.702' E
Elevation 635 m at the base of the outcrop
Stop 4: Following a trail from above the previous stop towards the top of the hill we see an outcrop approximately 4 ft thick that extends for approximately 30 feet. A single flow is seen here.
Latitude 18˚31.847' N
Longitude 73˚48.880' E
Elevation 643 m
Stop 5: We continue to ascend up the hill along a walking path and reach the highest point at Panchwati hill / Vetal tekdi where we see vertical faces of an abandoned quarry. The quarry itself covers an area of 1-2 sq. km and the center of the quarry is being recharged and developed as a lake.
We collected samples from several locations here (shown below). We observed a single basaltic flow, unweathered and massive. We assume this to be flow 4. Note that we did not observe the contact between flows 3 and 4 during our field traverse.
