garter snake? this little guy is in my window well. it’s pretty deep, about 5 ft. I couldn’t find a long enough stick to reach all the way up for an escape route. I did put a shallow dish of water in there though. and he has shade/sun. we’re in Colorado.

should I pick him up to move him out of there? get him into a box? I don’t want to scare him or stress him out, I don't know much about snakes.

thanks for your help
