The ridge that Clifton lies upon, descends from &lt;a href="Tauhinukorokio%20/%20Mount%20Pleasant"&gt;Tauhinukorokio / Mount Pleasant&lt;/a&gt; to end in a coastal cliff at the western end of Sumner beach. The cliff overhangs the road between Sumner and Moncks Bay that has been built along the beach. This area by the beach is now known as Peacocks Gallop because John Thomas Peacock would gallop his horse when riding along this section of road on account of his fear of being hit by falling rocks. Earthquakes in 2011 and later in 2016 caused the cliff edge to collapse and recede so much that several clifftop houses were undermined and severely damaged, or left perched precariously on the cliff edge. Shipping containers were stacked two-high on the main road below to protect it from further rockfalls and these subsequently became an impromptu roadside art gallery.
