Viewed from trail to Daisy Geyser & from Castle to Morning Glory trail. No eruptions. Areas around vent & to-the-north runoff channel have curled-upward microbial mats from desiccation. Likely no eruptions from Round Spring Geyser for some time. 1503 - as seen from main trail, there is water in the basin, but it is at a low level, with bubbling and occasional blipping. |
