Orchids in Wragg's Quarry

There are dozens of flowering spikes of orchids appearing in Wragg's Quarry at the moment. When they first appeared around 2011 I'm sure they were all Northern Marsh Orchids but now there appear to be a wide range of hybrids with what looks like Heath Spotted Orchid.
Many of the hybrids are tall flowering spikes which is a feature of hybridisation.
What ever they are there are some superb examples!
