It's a little bit before high noon. You spent most of the early morning traveling (Let's say sixish to ten?), spent an hour searching, and now it's about eleven in the morning. So yeah, still daylight. The ravine entrance however is entirely voided of light. The light from the entrance is hardly enough to illuminate the underground area. Makes sense, giving what lives down there.

I meant for the sake of taking off again. Also, while not superhuman Alaira's senses are very, very keen. She doesn't have night-vision, but she can see pretty well.

Unless she can rely solely on scent or hearing in a small enclosed underground area, your visibility is next to none if you don't bring your own lightsource.
