near the base”. About its late Whaingaroan (about 27 million years ago) creation, it says, “The change from estuarine, shallow brackish water conditions (Mangakotuku Formation), to fully marine, open sea, aerobic conditions (Glen Massey Formation) is evidenced by near shore accumulation of the bioclastic Elgood Limestone, onlap of the succeeding Dunphail Siltstone, and subsequent deposition of Ahirau Sandstone in an inner to mid shelf environment.” Pakihi is a Māori term now commonly used to describe poorly drained, infertile land. Much of the watershed of Lake Disappear was podocarp forest but is now mostly sheep and beef farms, with Te Uku
the next valley with Bridal Veil fall] drains underground through limestone (Elgood Limestone). During times of prolonged heavy rain, water backs up behind the outlet to form a sizable lake over what are normally dry alluvial flats.” Elgood Limestone (an outcrop is in the photo - see Gallery - to the left) is part of the Glen Massey Formation. The geology guide describes it as, “forming prominent bluffs or surface outcrops displaying solution channels, lapiez, and sinkholes, and is everywhere a light grey, flaggy limestone containing up to 95% CaCO. Glauconite is common throughout, together with Mesozoic pebbles and greensand

It has also been described as a solution lake. The south end can be seen from Kawhia Rd and, when the north end is full, it can be seen from the point which is at
the island is composed of limestone pavements with crisscrossing cracks known as "grikes", leaving isolated rocks called "clints". The limestones date from the Visean period (Lower Carboniferous), formed as sediments in a tropical sea approximately 350 million years ago, and compressed into horizontal strata with fossil corals, crinoids, sea urchins and ammonites. Glaciation following the Namurian phase facilitated greater denudation. The result is that Inishmaan is one of the finest examples of a Glacio-Karst landscape in the world. The effects of the last glacial period (the Midlandian) are most in evidence, with the island overrun by ice during this glaciation.
Lake Disappear Lake Disappear is an intermittent lake (see also Turlough (lake) and Polje) situated in the North Island of New Zealand, just over 20 km from Raglan, 4 km beyond Bridal Veil waterfall. It has also been described as a solution lake. The south end can be seen from Kawhia Rd and, when the north end is full, it can be seen from the point which is at the end of Plateau Rd on the Pipiwharauroa Way. It is the largest known polje in the country. Lake Disappear lies in a valley dammed by a lava flow (similar to
