Inferno Crater Lake, Waimangu, one of the largest hot springs in New Zealand, displays vigorous cyclic behavior in lake level and temperature. It provides a natural small‐scale laboratory for investigating the geo‐electrical signature of fluid flows. We measured self‐potential and electrical resistivity to see whether the huge variations of fluid volume, approximately 60,000 m3 during a mean cycle period of 40 days, could be detected. Electrical resistivity measurements revealed spectacular changes over time, with the medium becoming more conductive as the lake receded. This result is consistent with analog models, where the vapor phase is replaced by liquid at recession. The self‐potential survey did not detect temporal changes related to fluid movements. This can be explained by the pH of the pore water (∼2.3), which is close to the point of zero charge of silica.

“…1C), located 300 m to the NE, follows a 40‐day cycle with the water surface in the crater rising slowly until it reaches a level where it flows through a outflow channel into Hot Water Creek for a few days (Seward & Sheppard, 1986; Scott, 1992, fig. 3; 1994; Glover et al. , 1994).…”

“…Superimposed on these climatic fluctuations is a cyclic variation in water level that is related to the unique hydrothermal relationship between Frying Pan Lake and Inferno Crater Lake (Lloyd, 1973(Lloyd, , 1974Scott, 1992Scott, , 1994Glover et al, 1994). Inferno Crater (Fig.…”

“…The water level in the crater then drops to its lowstand position and the cycle begins again. Water discharge from Frying Pan Lake decreases while the water is flowing out of Inferno Crater Lake (Lloyd, 1973(Lloyd, , 1974Seward & Sheppard, 1986;Scott, 1992Scott, , 1994Glover et al, 1994). Then, while the water level in Inferno Crater Lake falls, the outflow from Frying Pan Lake increases.…”

Lilypad stromatolites, up to 3 m long and 1·5 m wide, were found to be actively growing in the shallow marginal waters of Frying Pan Lake and its outflow channel. These stromatolites, composed of Phormidium (> 90%), Fischerella, and a variety of other microbes, develop through a series of distinct growth stages. Dark green microbial mats cover the floor of the outflow channel and give rise to columns of various sizes and shapes in the shallower marginal waters. Once the columns reach the water level, the mats spread laterally to form a lilypad stromatolite. The lilypads are characterized by a raised, dark green rim, 4–5 mm high, that encircles a flat interior covered with a distinctive orange‐red mat. The microbes forming the columns and lilypad plate are being actively silicified. The stromatolites are formed of: (i) flat‐lying Phormidium filaments (P‐laminae), (ii) upright filaments of Phormidium that are commonly associated with Fischerella (U‐laminae), and (iii) mucus, diatoms and pyrite framboids (M‐laminae). P‐laminae dominate most of the columns, with tripartite cycles of P‐, U‐, to M‐laminae being found mostly in the upper parts of the stromatolites. The transition from the P‐ to U‐laminae is marked by a change in the growth pattern of the Phormidium and branching of Fischerella, which was probably triggered by a change in environmental conditions. In the Frying Pan Lake outflow channel, this change may be related to fluctuations in water level and flow rates that are caused by periods of heavy rain, seasonal changes, long‐term variations in rainfall, and/or the unique 40‐day hydrological cycle that exists between Frying Pan Lake and Inferno Crater, which is a nearby hydrothermal crater lake.
