  (these two pictures were taken by me above the natural history museum) this week's assignment was to see a volcanic geographic feature, and a quick google search told me Morro Rock is a volcanic plug. I didn't go up to the rock this time, but I've been there plenty of times to know that the rock looks like.  it looks like it's made of granite (an igneous intrusive rock) and is a protected space for Peregrin falcons that nests in the rocks.

Marmalade likes this fake rock hide and it is a warm space as it sits below the heat lamp, I've also seen her sit on top of it.  the lamp is on an adjustable switch, though I typically don't mess with adjusting it, it's either on or off. I leave the heat pad on all the time so there's always a warm space.
