Uncharted lands

You jump rock to rock. They're sturdy and secure. A few jumps in, and one cracks, falling into the lava. You scramble at the surface just enough to save yourself from falling in with a little help of the guide. The lava sputters, splashing you across your right back inner leg. The lava singes through your fur, leaving a deep burn about the size of a wolf's paw (5in x 4in). Ouch! That's gonna leave a scar.

Across the lava room stands a flat piece of smooth stone, so level and flat, it is as if thousands of paws had worn it over time. It looks cool to the touch and vaguely important. Surrounding it is a mote of lava, separated only by sharp stalagmites that impale it to point towards the open ceiling. There is no discernible path across. You know you must get there one way or another, but you're not sure you'll be able to go back the same way you came if you cross.

What do you do?
